Abstract:
A lens drive device comprises: a fixing part disposed away from the movable part; a cover for covering the movable part in the direction of an optical axis; and suspension wires for supporting the movable part relative to the fixing part, one ends of the suspension wires being secured to the fixing part and the other ends being secured to the movable part. The movable part is configured so as to be provided with: a damper material disposed so as to come in contact with the suspension wires; a stopper protrusion provided near a portion of the light-receiving-side surface where the other ends of the suspension wires are secured, the tip end of the stopper protrusion facing the inner surface of the cover in the direction of the optical axis; and a flow-stopper part stopping a flow of the damper flowing.
