- the optical fiber 42 is inserted into the pipe-shaped protective member 46, and the protective member 46 is fixed to the circuit board 43.
- the optical fiber 42 is fixed to the circuit board 43.
- the circuit board 43 must have a space for fixing the protective member 46, and this prevents the circuit board 43 from being downsized (in other words, the optical switch device 40 from being downsized). Then there is a problem.

The optical fiber 2 bends downward due to its own weight, and the optical fiber 2 hangs down from the optical switch body 41. Since the bare optical fiber portion is fragile, the problem that the bare optical fiber portion is broken is liable to occur when bent. Therefore, when transporting the optical switch main body 41 to which the optical fiber 42 is fixed, it is necessary to pay close attention so that the bare optical fiber portion of the optical fiber 42 does not break. There is a problem that production efficiency is bad.
