Abstract

PURPOSE:To provide a miniature, and mechanical stable photo coupler of less adjusting portions at the time of production by selectively forming portions of a large refractive index to a transparent sheet to make optical guides and forming a photo coupling part at the portion where the optical guides intersect.
