Abstract
An optical fiber guide part fixes optical fibers optically connected to optical waveguides of an optical waveguide device and is adhesively fixed to the optical waveguide device. The optical fiber guide part includes a V-grooved substrate, in a surface of which plural V-grooves are formed in parallel to one another, a lid member fixed to a top of the V-grooved substrate such that the V-grooves are exposed in a neighborhood of at least that end face of the V-grooved substrate which is on a side of the optical waveguide device, and a lid member fixed to an exposed part of the V-grooves of the V-grooved substrate, pressing, from above, the optical fibers inserted in guide holes formed by the V-grooves and the lid member placed on the V-grooves.
