Optical waveguide connecting structure, optical element mounting structure and optical fiber mounting structure

摘要

Provided is an optical waveguide connecting structure, having a first optical waveguide film cut in such a manner that a first core layer surface is exposed along an optical path direction in a slightly slant section forming an angle of about 5° or smaller, and a second optical waveguide film in which a second core layer is formed at a position opposed to the exposed surface of the first core layer in a slightly slant section forming an angle of about 5° or less with an optical path of the first core layer. The first core layer and the second core layer are connected at approximately the same height position from a reference surface.
