ABSTRACT:
A transparent composite material is able to promote visibility in a transparent coordinate input device due to the reflection of display light while the generation of an interference fringe at an input operating time is restrained. Many ridge portions extending in one direction are formed on the surface of a first transparent resistance film. Such ridge portions are projected stripes formed in a triangular shape in section, and are constructed by alternately forming one set of slanting faces on the surface of the first transparent resistance film.
