Coordinate input device having high transmittance

A coordinate input device comprising:

• an upper electrode comprising a transparent resistive layer formed on the lower surface of a flexible transparent film;
• a lower electrode comprising a transparent resistive layer formed on the upper surface of a substrate comprising transparent glass;
• a thin film comprising a transparent insulating material having a plurality of holes, said plurality of holes being spaced so as to form a grid pattern;
• and
• a plurality of spacers comprising an insulating material provided on the thin film;
• wherein the upper electrode and the lower electrode are opposed to each other with the spacers therebetween so that the upper electrode and the lower electrode conduct when the upper electrode and the lower electrode are brought into contact with each other through the holes,
• wherein each of said holes has an opening of at least 30 μm and not more than 200 μm, and a spacing between adjacent holes of at least 30 μm and not more than 200 μm, and
• wherein the thin film has a lower refractive index than that of the lower electrode, the thin film having a refractive index of between 1.0 and 1.8.
