Abstract
Provided is a key sheet which can effect reliable fixation inside a casing without occupying a large space, and includes key tops having large operating surfaces. A sheet surface of a base sheet is set substantially the same in size as a projection surface in a depressing direction of a key top group, and a frame-shaped elastic fixation portion is formed at an outer edge of the base sheet. Thus, a mounting space for a key sheet inside a casing can be contained within a range of the projection surface in the depressing direction of the key top group, and the key sheet can be firmly fixed to a circuit board. The key top group is the same in size as the base sheet. Thus, the key sheet including key tops having large operating surfaces can be realized.
