An electric shaver includes net-shaped outer blades; and inner blades sliding reciprocally over an inner side of the outer blades as detachably connected with driving units driven by a motor. Each of the inner blades includes a blade plate having an inversed-like-U shape seen from a longitudinal direction in parallel with a reciprocating sliding direction; and a blade holder having attaching portions to be attached to the blade plate in longitudinally defined end regions, wherein connection portions to be detachably connected with the driving units are provided at the blade holder in a longitudinally defined center region, and, when dissembling the blade holder from the driving units, anti-detach portions are provided to thereby prevent separation of the blade holder in the longitudinally defined center region from the blade plate in the longitudinally defined center region due to a tensile load between the connection portions and the driving units.
