An actuator (30) which drives a lens frame (18) in an optical axis direction is constructed by piezoelectric elements (32A, 32B), driving members (34A, 34B), and a pressing spring (36). The piezoelectric elements (32A, 32B) are placed at opposite sides with a driven plate (26) therebetween, and the driving members (34A, 34B) are fixed to the respective piezoelectric elements (32A, 32B). The driving members (34A, 34B) are pressed against the driven plate (26) from both sides by the pressing spring (36).
