The raids were conducted in Rafah, Al-Arish and Sheikh Zawayed cities between April 20 and 30, said army spokesperson Brigadier General Mohamed Samir.
He said 133 militants were arrested, while 51 militant hideouts were destroyed during the raids.
About 130 unlicensed vehicles and motorcycles used by militants to carry out attacks on police and army personnel were also destroyed, the spokesperson said in a statement.
The restive North Sinai region has witnessed several violent attacks by militants since the January 2011 revolution that toppled president Hosni Mubarak.
More than 500 security personnel have been reported killed in militant attacks since then.
The military has launched security campaigns in the area, arrested suspects and demolished houses that belonged to terrorists, including those facilitating tunnels leading to the Gaza Strip.
