PROBLEM TO BE SOLVED: To provide an inexpensive and compact optical switch apparatus in which light loss is reduced. SOLUTION: The optical switch apparatus has: an input optical fiber 102 and output optical fibers; a grating 107 which demultiplexes an optical signal into a plurality of optical signals having different wavelengths; a plurality of movable mirrors 108a or the like which are respectively tilted to reflect the respectively demultiplexed optical signals and to properly direct the optical signals to the output optical fibers 103; a mirror angle detector 109a or the like which detects the respective tilt angles of the respective movable mirrors 108a or the like; a table 111 which correlates the wavelength numbersλno for discriminating the optical signals having a plurality of wavelengths and the output destination number OUTno for discriminating the input optical fiber 102 and the output optical fibers 103 to the tilt angles of the respective movable mirrors 108a or the like; and a control circuit 110 which performs a feedback control of the movable mirrors 108a or the like so that the tilt angles AD output from the table 11 and the output from the mirror angle detector 109a or the like coincide with each other.
