ABSTRACT:
An optical waveguide device including a package housing having an element mounting surface, an element inserting groove opening to the element mounting surface, and a cutout as a space opening to an inner surface of the element inserting groove; and an optical waveguide element having a dielectric substrate, an optical waveguide formed in a surface of the dielectric substrate, and an electrode formed over the surface of the dielectric substrate, the optical waveguide element being inserted and fixed in the element inserting groove of the package housing by using an adhesive. The cutout opens also to the element mounting surface. In applying the adhesive to the bottom surface of the element inserting groove and inserting the optical waveguide element into the element inserting groove, the adhesive flows into the cutout and is prevented from flowing up to the element mounting surface. Further, a working space for application of the adhesive to the bottom surface of the element inserting groove can be ensured by the cutout.
