特徴とする光結合装置。 The device detects whether or not an object to be detected has passed without contact, and includes a light-emitting element, a light-receiving element, a light-emitting side transparent resin body formed by primary molding the light-emitting element with a light-transmitting resin, and the light-receiving element. A light-receiving side transparent resin body formed by primary molding the element with the light-transmitting resin, and the light-emitting side transparent resin body so that the light-emitting side transparent resin body and the light-receiving side transparent resin body are optically coupled. and a light-shielding resin body formed by secondary molding the light-transmitting resin body on the light-shielding resin body and the light-receiving side with a light-shielding resin, the light-emitting element is driven in pulses, and the light-receiving element is synchronized with this driving to detect whether or not the object to be detected passes. A light modulation synchronous drive circuit is provided for detecting the light, a passage hole is formed for passing the object to be detected through the light-shielding resin body, and the light-emitting side transparent resin body and An optical coupling device characterized in that light-receiving-side transparent resin bodies are arranged to face each other, and each lead terminal of the light-emitting element and the light-receiving element is drawn out in a direction perpendicular to a passage direction of an object to be detected.
