Abstract
An optical waveguide having a plurality of optical paths is formed on a substrate. A reflection mechanism is arranged above the optical waveguide. The reflection mechanism includes mirror components, each of which has an inclined reflective surface, and a mask having a plurality of openings. Laser is irradiated to the mirror components and optical path conversion inclined surfaces are formed in the plurality of optical paths at the same time by the laser reflected on the mirror components.
