PROBLEM TO BE SOLVED: To provide a liquid drive type optical switch which is free of variance in the amount of refractive index matching liquid in a groove for optical path switching. SOLUTION: A space 12, which swells in a bump shape, is formed halfway in an injection groove 11. Hence, when resin 13 for sealing is injected from the outside, after a fixed amount of refractive index matching liquid has been injected into the groove 5 for optical path switching, the resin 13 enters to up to the bump-shaped space 12 to seal it, so that the amount of the refractive index matching liquid is prevented from varying. |
