摘要:
A method is provided for producing an objective lens actuator in which a first resin portion which is a stationary portion and a second resin portion which is a movable portion on which an objective lens is to be mounted are integrally formed to plate-like bases in which a plurality of elastic support portions for movably supporting the movable portion relative to the stationary portion in a direction of an optical axis of the objective lens are formed in parallel with each other, so that the first resin portion and the second resin portions are connected to each other by the elastic support portions. At the same time, connecting portions provided between each of the elastic support portions and each plate-like base portion are formed so as not to overlap each other as viewed in the direction of the optical axis of the objective lens. The plurality of elastic support portions are cut away from the bases at the connecting portions.
