The bomb exploded in Al-Arish city of North Sinai when the police vehicle passed by it, killing a police officer and injuring other, according to a statement by the Minister of Interior.
The North Sinai region has seen many militant attacks since January 2011 revolution that toppled long-time dictator and ex-president Hosni Mubarak.
The attacks targeting police and military increased after the ouster of Islamist ex-president Mohamed Morsi in 2013.
Over 500 security personnel have been reported killed since then.
