摘要：PROBLEM TO BE SOLVED: To provide an optical waveguide circuit that can readily achieve optical coupling between an optical waveguide and an optical element.SOLUTION: An optical waveguide circuit is equipped with cores 5 to 8, an optical waveguide 3 so formed in a shape as to have a clad surrounding these cores 5 to 8, a shading film 15 formed over part of the surface of the clad, and two or more light transmitting areas 11, 12 and 16 formed over the shading film 15. The two or more light transmitting areas 11, 12 and 16 are made consistent in positional relation to aligning light output units 21 to 23 that are disposed over the lower face 20au of an optical element 20 mounted on the clad and output two or more aligning light rays.SELECTED DRAWING: Figure 1
