After a guide pin is inserted into the guide pin insertion hole from the back surface side of the housing, a forming jig is brought into contact with the back surface side of the housing to provide a guide for forming an optical fiber on the housing. Mounting the optical component on the body,
Form the optical fiber along the guide pin, connect the optical components with the optical fiber,
The optical fiber wiring method according to claim 6, wherein the forming jig is removed from the housing after the optical fiber is formed. A printed circuit board having guide pin insertion holes formed so as to match the guide pin insertion holes is disposed on the housing,
While the guide pin of the forming jig is inserted into the guide pin insertion hole of the case and the printed circuit board from the back side of the case, the forming jig is brought into contact with the back side of the case and the optical fiber is attached to the case. After providing the guide for forming, mount the optical component on the housing,
The optical fiber wiring method according to claim 6 or 7, wherein the optical fiber is formed along a guide pin.   The optical fiber wiring method according to claim 7 or 8, wherein after forming the optical fiber, the guide pin is removed from the guide pin mounting hole, and the jig plate of the forming jig is removed from the housing. When attaching a large number of optical components to the housing and connecting these optical components with optical fibers,
In the housing, a plurality of guide pin insertion holes are provided according to the optical fiber wiring route,
The jig plate of a conductive forming jig comprising a jig plate in which a large number of guide pin mounting holes are formed on the back side of the housing and a guide pin that can be freely attached to and detached from the guide pin mounting holes. Contact
After providing a guide for inserting an optical fiber into the housing by inserting the guide pin from the front surface side of the housing into the guide pin mounting hole coinciding with the guide pin insertion hole, the optical component is mounted on the housing,
Form the optical fiber along the guide pin, connect the optical components with the optical fiber,
An optical fiber wiring method comprising removing a forming jig from a housing after forming an optical fiber. A printed circuit board having guide pin insertion holes formed so as to match the guide pin insertion holes is disposed on the housing,
The jig plate is brought into contact with the back side of the housing, and the guide pin is inserted from the front surface side of the housing into the guide pin mounting hole of the jig plate coinciding with the printed board and the guide pin insertion hole of the housing. After providing a guide for forming an optical fiber in the housing, the optical component is mounted on the housing,
The optical fiber wiring method according to claim 10, wherein the optical fiber is formed along the guide pin. The optical fiber wiring method according to claim 10 or 11, wherein after forming the optical fiber, the guide pin is removed from the guide pin mounting hole, and the jig plate of the forming jig is removed from the housing.
