PROBLEM TO BE SOLVED: To provide an optical deflector that reduces power source load by reducing electrostatic capacity and that prevents deflection displacement between incident light and emission light.SOLUTION: An optical deflector according to the invention comprises a pair of light incident/outgoing faces that sandwich an electro-optical crystal between a pair of parallel quadrangular electrode faces and that are perpendicular to the electrode faces and parallel to each other, each incident/outgoing face having a light non-reflection coat part and a high light reflection coat part identical in area such that light is made incident on the light non-reflection coat part and light made incident on the deflector is reflected from the high light reflection coat part. The deflection direction of light is perpendicular to the electrode face. |
