徴とする光結合装置。 A light-emitting element mounted on the light-emitting side lead frame and a light-receiving element mounted on the light-receiving side lead frame are arranged facing each other in a plane with a certain interval, and are optically coupled by molded resin. In an optical coupling device in which a signal is first converted into light by a light emitting element, and this light is converted back into an electric signal by a light receiving element and outputted, the light emitting element mounting part of the light emitting side lead frame and the light receiving element mounting part of the light receiving side lead frame are provided. An optical coupling device characterized in that a recess is formed at the tip of the part, and a light guide is installed between the recess to efficiently reflect light emitted from a light emitting element and guide it to a light receiving element.
