摘要

An optical waveguide film includes: an optical waveguide film main body including an optical waveguide core through which light travels and a cladding portion that surrounds the optical waveguide core and has a lower refractive index than that of the optical waveguide core; an electric wiring portion including silver or a silver alloy and formed on at least a part of a principal surface of the optical waveguide film main body; and a protective layer including a titanium layer or a titanium alloy layer and disposed to cover the electric wiring portion.
