The army targeted areas in Sheikh Zowayed and Rafah with aerial and ground forces, security sources said.
Twenty-five shelters, headquarter and two houses belonging to terrorists were destroyed during the raids, they added.
Egypt's Sinai has witnessed many violent attacks by militants since the January 2011 revolution that toppled the 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.
