The present invention provides a photocoupler capable of reducing the mount area required to mount the photocoupler on an object by eliminating a structurally unnecessary portion, and an apparatus and method for fabricating such a photocoupler. A light-receiving device and a light-emitting device placed on a pair of lead frames are embedded in a primary mold body made of a transparent resin, and the primary mold body is embedded in a secondary mold body made of a light-shading resin, to form the photocoupler. The lead frames are bent inside the secondary mold body, and the outer side of the terminal portion of each lead frame, ranging from the bent position to the top end, is exposed at the secondary mold body.
