Claim 0:
1. An optical waveguide component comprising an optical waveguide provided on an upper surface of a substrate and including a core and a clad covering the core and an optical path conversion unit that is formed in a part of the optical waveguide and converts an optical path of an optical signal and inputs and outputs the optical signal to and from an optical element to be mounted, wherein
the optical path conversion unit comprises an input-output unit using as a mirror surface a local portion of an inclined surface on the side of the core in an inclined groove formed to be deeper than the core in a direction intersecting an emission direction of the optical signal in the core and perpendicular to a horizontal direction of the substrate,
an offset unit in the horizontal direction of the substrate is provided to communicate with the inclined groove on the side of an opposite inclined surface opposing the mirror surface in the inclined groove, and
the offset unit is formed such that a distance between a region exceeding the opposite inclined surface on an extension line of the core intersecting the mirror surface and the mirror surface is longer than a distance between a region other than the region exceeding the opposite inclined surface and the mirror surface.
