Abstract
A method of manufacturing an optical waveguide, includes preparing a light path conversion component including a structure in which a protruding portion having a light path conversion inclined surface is covered with a metal layer and the metal layer serves as a light path conversion mirror, and a structural body in which a core layer is formed on a first cladding layer and an opening portion is provided in an end side of a light path of the core layer, arranging the light path conversion mirror of the light path conversion component in the opening portion of the core layer, and forming a second cladding layer covering the core layer, wherein a light path of a light that propagates through the core layer is converted toward a first cladding layer side by the light path conversion mirror.
