光結合装置。 A connection part that is mounted on a mounting part that is wider than the lead part that inputs and outputs from the outside of the lead terminal for mounting a light emitting element and is formed wider than the lead part that inputs and outputs from the outside of the lead terminal for connecting the light emitting element. The light emitting side transparent resin body is formed by primary molding the light emitting element to be internally connected to the light transmitting thermosetting resin, and the lead part for external input/output of the lead terminal for mounting the light receiving element is formed wider. The light receiving element is mounted on a mounting part and is internally connected to a connecting part that is wider than the lead part that inputs and outputs from the outside of the lead terminal for connecting the light receiving element, and is primarily molded with the thermosetting resin. The side light-transmitting resin body, the light-emitting side light-transmitting resin body, and the light-receiving side light-transmitting resin body are placed facing each other at a predetermined interval, and are integrally sealed with a light-shielding thermoplastic resin except for the optical path window portion of the light-transmitting resin body. The light-shielding resin body is made of a thermoplastic resin having a heat deformation temperature higher than the melting temperature of solder, etc., and the mounting portion and the connection portion are light-transmitting on the light-emitting side. An optical coupling device characterized in that it is located between a resin body, a light-transmitting resin body on a light-receiving side, and a light-shielding resin body.
