A lens-equipped optical waveguide device for a touch panel comprises an optical waveguide including an under cladding layer and a plurality of cores; and a lens device having a mounting surface for placing the optical waveguide thereon and a lens formed in an end portion of the mounting surface. The mounting surface of the lens device includes an adhesive receiving groove formed therein, and the optical waveguide includes a through hole penetrating in the direction of the thickness of the optical waveguide and in communication with the adhesive receiving groove so that the bonding between the mounting surface and the optical waveguide with the adhesive is achieved by using the adhesive receiving groove and the through hole.
