PURPOSE: To provide a method for easily executing optical input/output coupling in a bending coupler with reliability relating to at least one optical waveguide body. CONSTITUTION: In this method for bringing at least one optical waveguide body (LW1) to a curved surface by a movable stamper (ST) and bringing the bending coupler (BK) capable of inputting and outputting light along the curved surface to the coupling position, the movement of the stamper (ST) is ended at a selectable operation position (AP) and the stamper (ST) is held at the operation position (AP). |
