摘要： In an embodiment of the present invention, in an optical coupling element comprising a light emitting element and a light receiving element, a transparent sealing portion for sealing these elements, an opaque sealing portion that covers the transparent sealing portion, and terminals that are connected individually to the electrodes of the light emitting element and the light receiving element and are drawn out from a side face of the opaque sealing portion, the creeping distance being the sum of the gap distance between these terminals and their opposite side faces and the distance between the bottom edges of the side faces, a creeping distance extension face for extending the creeping distance is provided between the bottom face and the side face of the opaque sealing portion, and the gap distance between the terminals and the edge formed by the bottom face and this creeping distance extension face is set to a specific distance.
