PROBLEM TO BE SOLVED: To ease the assembling process of an optical switch in which generation of insertion loss and reflection returning light beams is suppressed regardless of the changes in environmental temperature and an optical path is always switched in an effective manner. SOLUTION: The optical switch is provided with a base 19, an input side waveguide chip 2 and an output side waveguide chip 4 which are provided on the base, an input side silicon block 3 which is provided on the input side waveguide chip, an output side silicon block 5 which is provided on the output side waveguide chip. The end faces of the input side waveguide chip and the output side waveguide chip, which face each other, have an angle that is greater than 0 degree with respect to the vertical direction to the surface of the base. The input side silicon block and the output side silicon block are not arranged in the vertical direction with respect to the surface of the base in the gap between the input side waveguide chip and the output side waveguide chip. Thus, observation can be made from the top of the gap between the input side waveguide chip and the output side waveguide chip to ease the assembling process of the optical switch.
