OPTICAL WIRING SUBSTRATE AND OPTICAL AND ELECTRIC COMBINED SUBSTRATE

摘要

An optical wiring substrate enabling the easy alignment of the positions of the cores of an optical pin with the positions of the cores of an optical waveguide layer with a simple structure and an optical and electric combined substrate. The optical wiring substrate comprises an optical wiring layer (31) having optical waveguides (35) and the optical pin (32) is inserted into a hole (34) formed in the optical wiring layer and cutting a part of the optical waveguide. The optical pin comprises the cores (2) and a clad, and first recesses (5) are formed in one of its outer surfaces. Projections (33) used as guides for positioning the optical pin together with the recesses are formed on one of the wall surfaces of the hole.
