Abstract
An optical waveguide module has a planar type optical waveguide having at least one core, an optical fiber for connecting with the core of the optical waveguide optically, and an optical element for connecting the core of the optical waveguide optically. The optical waveguide includes a groove for allowing an optical fiber to be inserted thereinto and aligning the optical fiber with the core to connect the optical fiber and the core optically. A first edge of the optical waveguide, which traverses the core, is tapered and an edge of the core, which is exposed in the first edge of the optical waveguide, is formed as a reflection surface. A planar type optical element is mounted as the optical element at a position that is opposite to the reflection surface to connect the planar type optical element with the core optically through the reflection surface.
