PROBLEM TO BE SOLVED: To provide an optical switch which can separately output wavelength multiplexed light. SOLUTION: A filter 3 in which a plurality of interference filters 3a to 3c are juxtaposed is arranged in a groove 2 intersecting optical waveguides 14a and 14b, and three-phase driving voltage is applied to a plurality of electrodes 4. Thus, the filter 3 is moved to a desired position by using an inductive charge type static electricity driving method using electrostatic force generating between the moving piece part 3d of the filter 3 and the electrode 4 working as a stator.
