The Court of Cassation also upheld life sentences against two other Brotherhood leaders including Mahmoud Ghozlan, a Brotherhood spokesman, along with five-year prison terms for 14 others, defence lawyer Abdel Moneim Abdel Maksoud told AFP.
Badie's life sentence -- his third -- and the court's other rulings are final and cannot be appealed.
The court has cancelled scores of death sentences against Morsi supporters, including against the deposed president himself.
Egypt designated the Brotherhood a "terrorist" organisation in December 2013.
