PROBLEM TO BE SOLVED: To provide a easily mountable unit in a unit for switching evanescent light which leaks out from all reflective surfaces of a light guide. SOLUTION: The shape of a light guide 1 for guiding incident light 2 is made into a shape having a connection body 61 extended to the side of a switching device 50. This body secures easily a space for wiring a bonding pat 71. Furthermore, a compact device 50 convenient for assembling, storage, and distribution in which micro structures such as an actuator 6, an optical element 3 are protected by a cover can be realized by joining the connection body 61 after manufacturing the connection body 61 separately with a main body 60 of the light guide 1. |
