Coordinate data input device

A coordinate data input device, comprising:

• a pair of detecting members, each including an insulating substrate, a resistance film provided on said insulating substrate and a conductor formed on said insulating substrate to be electrically connected with said resistance film, said pair of detecting members being arranged in a face-to-face manner such that said respective resistance films of said detecting members are opposed to each other;
• a spacer disposed between said pair of detecting members to define a gap between said respective resistance films, said spacer permitting said resistance films to be shorted with each other when at least one of said detecting members is deformed;
• and
• a ground conductor element formed on at least one of said pair of detecting members, said ground conductor element being located so as to be spaced from and substantially surround said resistance films and conductors of both of said detecting members.
