| Zusammenfassung: | The present invention relates to an optical waveguide film that has a high optical coupling efficiency at a light input portion and an excellent flexibility at least a part of the film. Specifically, the present invention provides an optical waveguide film that has a core and a clad comprising a resin and has a light input portion, wherein there is a portion having a thickness smaller than that of the light input portion. Further, the present invention provides an electrical and optical hybrid film in which an electrical wiring board is joined to the optical waveguide film or an electronic device in which these films are built in. |
