Abstract
An optical member driving device having a movable member formed integrally with a frame member holding an optical member, without requiring a reinforcement of any abutting regions on the driving friction member is comprising a driving friction member capable of a reciprocation in an axial direction thereof, a movable member formed integrally with a frame member holding an optical member which engages frictionally with the driving friction member, wherein the movable member is made from fiber reinforced polyphenylene sulfide formed with an injection molding process, and an engaging surface of the movable member abutting on the driving friction member is processed so as to remove some material after the injection molding process.
