<p><P>PROBLEM TO BE SOLVED: To provide an optical waveguide which can be used under a condition of intense outside light without increasing thickness of an optical waveguide (frame section of an optical touch panel), and the optical touch panel using the optical waveguide. <P>SOLUTION: The optical touch panel can protect a core 12 from outside light 17 without increasing the thickness in the frame section by providing a recessed part 14b on an over-cladding layer 14 in the optical waveguide 10 to fit the recessed part 14b into a frame body 15 of the optical touch panel. In the optical touch panel, alignment precision of the optical waveguide 10 is improved to easily obtain a high transmission efficiency because the optical waveguide 10 and the frame body 15 are integrated. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
