摘要： A flow of a resin which is injected for insert-molding a wiring plate into an end face of an optical fiber positioning component is regulated by regulating portions disposed in side portions of a die. Therefore, leads of the wiring plate can be prevented from being fixed while remaining to be positionally displaced by the force of the flowing resin. As a result, three-dimensional electrical wirings can be formed easily and correctly.
