When a resin 59 to form a molded body 20 is poured and a lead frame 30 is attached to a front end face 21 of the molded body 20 by insert molding, protective leads 32 provided on both outsides of a lead pattern 31 of the lead frame 30 moderate the flow of the resin 59 and the force acting on the lead pattern 31 is decreased, so that misregistration of the lead pattern 31 can be prevented. Accordingly, the inserted and molded lead frame 30 can be wired on the front end face 21 of the molded body 20 for easily accomplishing three-dimensional electric wiring.

After a wiring plate 30 having a plurality of leads 31 been insert-molded to an edge face 21 of a molded article 20, unwanted portions of the wiring plate 30 are cut, thereby enabling easy three-dimensional wiring. As a result, an electrode terminal section 43 of a photoelectric conversion element 41 disposed opposite an end face 11b of an optical fiber 11 can be electrically coupled to an electrical wiring section 23 of an optical coupling part 10.
