Abstract:
1. A method for manufacturing an optical waveguide, comprising: (A) temporarily affixing one side of a layered film including alternate layers of a core layer and a cladding layer to a cutting base material, and cutting the layered film in a thickness direction from a side of the layered film opposite to the cutting base material so as to form a groove that penetrates through the layered film but does not penetrate through the cutting base material and a plurality of core portions; (B) attaching a transfer base material provided with an uncured curable resin layer to a surface of the cut layered film at the side opposite to the one side affixed to the cutting base material with the curable resin layer disposed between the transfer base material and the surface of the cut layered film; (C) curing the curable resin layer in order to peel the cut layered film from the cutting base material while maintaining spacing between the plurality of core portions, and in order to transfer the cut layered film to the transfer base material; and (D) enclosing with a cladding material the plurality of core portions, the spacing being maintained by the cured resin layer.
