Abstract:
1. An optical waveguide film comprising: an optical waveguide film main body having an optical waveguide core through which light is propagated, and a cladding portion that encloses the optical waveguide core and has a lower refractive index than that of the optical waveguide core; and an electric wiring layer formed on at least a part of a principal surface of the optical waveguide film main body, wherein the principal surface is an outer surface of the optical waveguide film main body, wherein the electric wiring layer is a metal layer, wherein the optical waveguide film has, at least at one end portion in a longitudinal direction thereof, a slanted surface that forms an optical path diverting portion at which an optical path of light propagated through the optical waveguide core is diverted, and wherein a layer of the same metal as that of the metal layer serving as the electric wiring layer is provided, as a reflecting layer, on the slanted surface.
