According to the present invention, there is provided a pushbutton switch cover sheet (11) providing a unique design. A pushbutton switch cover sheet (11) is provided with an operation plate (12) of metal or hard resin having dividing grooves (14) defining depressing operation members (15) capable of displacement through depression. Therefore, there is no need to provide the casing of the apparatus with a frame defining key tops, making it possible to impart a novel design to the apparatus. The operation plate (12) is formed as a thin plate, so it is possible to reduce a thickness of the apparatus as a whole. Further, the dividing grooves (14) are provided with in-groove protrusions (24) protruding into the dividing grooves (14) and groove filling members (64) fixed to the groove inner side surfaces and formed of a rubber-like elastic material, thereby making it possible to provide a pushbutton switch cover sheet (11) of a high level of safety in which there is no fear of fingers being injured by the dividing grooves (14).
