PROBLEM TO BE SOLVED: To propose the structure of a compact MEMS light switch of one-input/two-output type in which the optical path length of two switching optical paths and other optical conditions are homogenized and optically homogenized emitting light beams are output. SOLUTION: The end parts of three optical waveguide means are supported in parallel to one another on a substrate, the end part of a central optical waveguide means is used as one input port of the light switch, the end parts of the two optical waveguides neighboring on both sides are used as a first and a second output ports, the emitting light from the input port is switched, reflected and deflected to either of the first output port side and the second output port side with a first movable mirror and a second movable mirror which alternatively inserted at the positions which are located at the same distance from the end face of the input port of the optical path, the light beams from the first movable mirror and the second movable mirror are reflected and deflected with a first fixed mirror and a second fixed mirror, made parallel to the emitting light beam from the input port and reversed in direction, and respectively combined to the first and the second output ports.
