The backers of Morsi are facing a deadly crackdown launched by the military-installed authorities since his ouster in July, with hundreds of people killed and thousands arrested.
The sentence was delivered in the second hearing of a trial which began on Saturday in Minya, south of the capital.
Of those sentenced, 153 are in detention and the rest are on the run, the sources said, adding that 17 others were acquitted. The verdict can be appealed.
Those sentenced are among more than 1,200 Morsi supporters on trial in Minya. A second group of about 700 defendants will be in the dock on Tuesday.
They are accused of attacking both people and public property in southern Egypt in August, after security forces broke up two Cairo protest camps set up by Morsi supporters on August 14.
They are also charged with committing acts of violence that led to the deaths of two policemen in Minya, judicial sources said.
The accused include several leaders of Morsi's Muslim Brotherhood, including its supreme guide Mohamed Badie.
Morsi, Egypt's first elected and civilian president, was ousted by the army on July 3 in a move that triggered widespread unrest across the deeply polarised nation.
Hundreds of people died in the August assault on the two Cairo protest camps and in subsequent clashes that day.
Rights group Amnesty International says at least 1,400 people have been killed in violence across Egypt since then, and thousands more have been arrested.
Morsi is himself currently on trial in three different cases, including one for inciting the killing of protesters outside a presidential palace while he was in office.
Morsi was removed after just 12 months as president following mass street protests against his rule amid allegations of power grabbing and worsening an already weak economy.

@Pakistani Muslim:
Going by the body count and methods, we will start with the Kashmiris!
There are some parts of this world that is going back in time while others keep with it. This bipolar phenomenon is likely to cause a great deal of friction in the future.
@vasan you are wrong here.read the judgment in case of a foal guru and it will open your eyes.i am not absolving afzal of his crimes but punishment is based on proofs...evidence. ..and just read the judgement to get the real picture. Still if it's beyond your grasp try to read arundhati Rai to get the truth.
This is jaw dropping horror! The Egyptian military regime is prepared to be ruthless and brutal beyond expectation in making sure its grip on power is not challenged. They sacrificed Mubarak in 2011 to release public pressure on the regime, but they have long since given up soft tactics.
@kk: Never heard that number united nation has put less than 400 human rights violation.
Saudis at their best
@Nikki:
Why is that? How about Pakistan coming to protect "these people".
@vasan how do u justify seventy thousand innocent kashmiris Martyred by indian soldiers
Excellent decision. Bangladesh and Egypt should continue cracking down on these elements. They are cancerous to society. Pakistan should take a lesson.
Who else then? Shame on you.@Professor:
This is the story of muslim countries. When afzal guru was hanged after proper judicial process for attacking Indian parliament, hue and cry was raised in Pakistan and some even proposed attacking India. Now that brotherly muslim country is hanging brotherly muslims en masse, what is Pak proposing to do. Watch from the sidelines, I guess.
Puzzling politics:
America should come to protect these people. Democratic world should not have diplomatic relations with Dictators.
Insane! when the house is not in order, all of these things happen.
jamat-e Islami should also be banned in pakistan like egypt and bangla-desh..
lol @Professor: It could be CIA or/and Mossad, but RAW can't pull such stunt even inside India. hahaha
In Pakistan, the situation is totally opposite. Over here Soldiers are being punished for their actions against the terrorists.
Please don't blame this on CIA, MOSSAD and RAW.
this has to be the biggest joke of this century..... seems like Egypt is yet again getting ready for another blood bath
Dictatorship at its best...
