子。 In an optical coupling device in which a light emitting element and a light receiving element pair mounted on a lead frame and arranged in parallel in one plane are resin-molded, a light transmission part between the light emitting element and the light receiving element is formed by forming a part that becomes an optical path. At the same time, the removed portion of the optical path is filled with a second highly transparent resin that transmits light from the transparent resin, and further, both of the resins are molded. An optical coupling element characterized in that the outer periphery of a light transmitting part is molded with a light-shielding resin.
