| 摘要 |
An object of the invention is to provide an optical coupling apparatus in which light-transmitting resin is prevented from entering a hole of a substrate, and a method for manufacturing the same. In this construction, a cushioning pattern is formed around each of the holes on the surface of the substrate. During a primary molding operation, a protrusion of an upper mold is brought into press-contact with the cushioning pattern formed around the hole of the substrate, so that the hole is blocked up perfectly, thereby preventing the light-transmitting resin from entering the hole.
