Abstract
An optical waveguide unit having board unit engaging vertical grooves and a board unit having engagement plate portions to be fitted in the vertical grooves and projections are individually produced, and the engagement plate portions and the projections are brought into fitting engagement with the vertical grooves of the optical waveguide unit. At this time, the projections are deformed to accommodate the tolerances of the components, thereby preventing wobbling and warpage of the board unit. Further, the vertical grooves of the optical waveguide unit are provided in proper positions with respect to a light transmission face of a core, and the engagement plate portions of the board unit are provided in proper positions with respect to the optical element. Therefore, the fitting engagement between the vertical grooves and the engagement plate portions permits proper positioning of the light transmission face of the core and the optical element for self-alignment.
