Abstract
An optical element module includes an optical element, and a plurality of actuator elements. In the module, each actuator element has an ion conductive polymer film and electrodes arranged on both sides of the film, and a whole of the actuator element is bent in a direction of thickness by applying a voltage between the electrodes, and the direction of the thickness of the actuator elements is a direction of an optical axis of the optical element, the actuator elements are arranged at equal intervals around the optical axis on a plane perpendicular to the optical axis, and a displacement due to the bend of one end part of at least one actuator element acts on one of a side surface and a bottom surface of the optical element to effect one of tilting and movement in the direction of the optical axis of the optical element.
