Abstract:
1. An optical element module comprising: an optical element; and a plurality of actuator elements; wherein each of said actuator elements has an ion conductive polymer film in a shape of a long and narrow plate and electrodes arranged on both sides of said ion conductive polymer film, and a whole of said actuator element is bent in a direction of thickness by applying a voltage between said electrodes, and the direction of the thickness of said plurality of actuator elements is a direction of an optical axis of said optical element, said plurality of actuator elements are arranged at equal intervals around the optical axis of said optical element on a plane perpendicular to the optical axis of said optical element (XY plane), and a displacement due to said bend of one end part in a direction of length of at least one actuator element acts on one of a side surface and a bottom surface of said optical element to effect one of tilting and movement in the direction of the optical axis of said optical element.
