Abstract:
1. A method of manufacturing an optical waveguide having a mirror face, the method comprising: laminating an uncured photocurable resin sheet for forming a core on a surface of a first cladding layer that has been formed on a substrate; forming a mirror face for guiding light to the core by pressing a die to the uncured photocurable resin sheet, the die being provided with a blade which possesses a single edge having, in a cross-section, an inclined angle of 45 degrees or a double edge having, in a cross-section, two 45-degree inclined angles, the die being pressed such that the blade substantially perpendicularly penetrates the photocurable resin sheet; after the mirror face forming by pressing the die, forming the core having the mirror face positioned at an end of the core, by selectively exposing the photocurable resin sheet to light, and developing the photocurable resin sheet; and forming a second cladding layer so as to bury the core.
