Claims

[Claims for Utility Model Registration] 1. A light-emitting element and a light-receiving element mounted on a lead frame, a light-emitting side light-transmitting resin body formed by covering the light-emitting element, and a light-receiving side formed by covering the light-receiving element. A light-transmitting resin body, and a non-light-transmitting exterior formed by integrally covering the light-emitting side transparent resin body and the light-receiving side transparent resin body, and the lead portion of the lead frame is attached to the exterior. 1. An optical coupling device characterized in that a lead-out portion is formed, and a connecting portion between the lead-out portion and a connector that performs input/output with the outside is sealed with a resin. 2. A light-emitting element and a light-receiving element mounted on a lead frame, a light-emitting-side transparent resin body formed by coating the light-emitting element, a light-receiving-side transparent resin body forming a coating over the light-receiving element, and the light-emitting element and the light-receiving element. A non-light-transmitting exterior is formed by integrally covering a side light-transmitting resin body and a light-receiving side light-transmitting resin body, and the lead portion of the lead frame serves as a pin of a connector for inputting and outputting external data. 1. An optical coupling device characterized in that the exterior casing and the connector are integrally molded.
