Abstract
The coordinate-inputting device comprises a base substrate, a first electrode formed on the substrate and made of a transparent resistor layer, a plurality of electrically insulating dot spacers formed on the first electrode and kept away from one another at intervals, a second electrode, which is provided in face-to-face relation with the first electrode, is electrically insulated therefrom through the dot spacers and is made of a transparent resistor layer, and a readily deformable film formed on the second electrode. The device has a glass layer formed on the film and made of a liquid glass. The glass layer serves as a protective layer and is hard enough to reduce damages on the surface of the device as is caused by frictional contact with an input member.
