SUBSTRATE HAVING OPTICAL WAVEGUIDE AND ELECTRIC CIRCUIT AND METHOD FOR MANUFACTURING THE SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To obtain a substrate having an optical waveguide and an electric circuit and improved in packaging density and the efficiency of light propagation. SOLUTION: The optical waveguide 3 and a photoelectric transducing element 4 having a light receiving part or a light emitting part on the side of the waveguide 3 are mounted on a substrate body 1 and a reflection member 2 opposed to the core part 3b of the waveguide 3 obliquely to the optical axis of the waveguide 3 and consisting of a lump-like metal optically connects light propagated through the waveguide 3 to the element 4.
