Execution sentences will be issued to minors without considering other options, Ahmad Mozaffari told the state-run news agency ILNA.
Mozaffari made the comments after Iranian courts issued execution sentences to a 15 year old and 16 year old, the report said.
The judge said one minor was sentenced to execution recently, despite the fact that examination by a government-appointed physician had shown that he was suffering from a psychiatric disorder.
State-run press have identified the 15-year-old on death row only by his first name Mohammad.
