Patent ID: 8842952

Claim:
An optical module comprising a transparent substrate through which light can pass, a photoelectric conversion element that is mounted on said transparent substrate and that emits light toward said transparent substrate or receives light having passed through said transparent substrate, and a support member that supports an optical fiber for transmitting light, said support member and said transparent substrate together forming an optical path between said photoelectric conversion element and said optical fiber, wherein: a positioning hole is formed in said transparent substrate; a positioning pin having a tapered surface is formed on said support member; said transparent substrate and said support member are positioned with respect to one another by inserting said positioning pin into said positioning hole along the optical axis direction of light between said transparent substrate and said support member and by making said tapered surface of said positioning pin contact the edge of said positioning hole without leaving any space therebetween; and an optical system of said support member is configured such that, in a state where said transparent substrate and said support member are in tight contact, light emitted from said photoelectric conversion element converges onto a point that is farther than an end surface of said optical fiber as viewed from the side of said photoelectric conversion element and that is located within the optical fiber.
