Abstract
An optical deflection element receives incident beam and deflects the incident beam with an arbitrary deflection angle. The optical deflection element includes a plurality of unit members which are successively stacked and each including an electrooptic layer, an electrode layer formed on a surface of each electrooptic layer, and an insulator layer formed on the surface of each electrooptic layer adjacent to the electrode layer, where a boundary between the electrode layer and the insulator layer is inclined to an optical axis of the incident beam.
