Disclosed is a thin key sheet that is relatively free from breakage due to depressing operation. When key tops are depressed, float-supporting portions of rubber moldings and a film sheet undergo deformation, and a depression load can be borne by both the float-supporting portions and the film sheet, so the load on the float-supporting portions is mitigated, making the float-supporting portions less subject to breakage. Further, since the film sheet exists between the rubber moldings and a resin plate, it is possible to prevent the rubber moldings from being rubbed against a side wall of a frame portion, making it possible to prevent breakage due to rubbing between the rubber moldings and the resin plate.
