ABSTRACT:
Disclosed is a film key sheet with a key top protruding from a resin film which allows a further reduction in thickness and provides a sufficient degree of clarity in visually recognizing a display portion thereof, and a method for manufacturing such a film key sheet. The film key sheet has a film removal hole piercing through the resin film, with a hole edge portion raised from the surface of the resin film being secured to the side surface of the key top. Thus, no resin film exists on the upper and bottom surfaces of the key top, so that it is possible to achieve a further reduction in thickness independently of the foldability of the resin film and drawing accuracy and to provide clarity in visual recognition of a display portion at the bottom of the key top.
