Abstract
In an optical touch panel of the present invention, at a light-emitting side, there is provided an optical waveguide device, in which a light input end of an optical waveguide laminate laminated by a plurality of optical waveguides is optically coupled to a two-dimensional light-emitting element. At a light-receiving side thereof, there is provided an optical waveguide device, in which a light output end of an optical waveguide laminate laminated by a plurality of optical waveguides is optically coupled to a two-dimensional light-receiving element.
