Three-dimensional wiring can be easily laid and an electrode terminating on a slanted surface can be easily formed. A photoelectric coupling assembly comprises a photoelectric conversion unit and a molded article. The molded article includes a hole to receive an optical fiber, a distal end surface being slanted to an axis of the hole, a side surface forming an acute angle with the distal end surface, and an electrode mounted to the distal end surface. The electrode has a first end terminating within the distal end surface and a second end having an end surface exposed on the side surface. A method includes holding a wiring plate having a lead in a state where a supported end of the lead is positioned on a side surface of the molded article and insert-molding the article, cutting the wiring plate from the article, and mounting the conversion unit on the distal end surface.
