ABSTRACT:
A photo-electric coupling device has a semiconductor light-emitting element and light-responsive element, the latter element receiving directly and approximately perpendicularly light emitted from the light-emitting element through its active edge including an edge of a P-N junction thereof. The light-responsive element and the light-emitting element are mounted on free-end portions of respective leads bent about 45.degree. out of a planar lead frame whereby a plane defined by the free-end portion carrying the light-responsive element is approximately perpendicular to a plane defined by the other free-end portion.
