A touch panel optical waveguide device which obviates the need for an alignment operation for alignment between light emitting cores of an optical waveguide thereof and light emitting means and alignment between light receiving cores of the optical waveguide thereof and light receiving means, and to provide a production method for the optical waveguide device. A recess (5) is provided in a longitudinally middle portion of an elongated optical waveguide (W) with its wall surfaces defined by end faces of light emitting cores (3), light receiving cores (3) and over-cladding layers (4). A mount member (10) including light emitting means (12) and light receiving means (13) fixed to a single substrate (11) is mounted in the recess (5) so as to achieve alignment between the light emitting cores (3) and the light emitting means (12) and alignment between the light receiving cores (3) and the light receiving means (13).
