| 摘要 | Provided is a stable key sheet in which, even if a key top is operated so as to be shifted sidewise, no excessive change, such as great tottering of the key top or overlapping of key tops each other, is caused. A key sheet (10) including: a key top (13) having a fixation protrusion (13b) protruding from a center of a bottom surface; and a base sheet (16) to which the fixation protrusion (13b) is fixed, further includes a stopper plate (17) having an opening (17a) through which the fixation protrusion (13b) of the key top (13) is passed and whose edge faces a side of the fixation protrusion (13b), in which, at a time of sidewise movement of the key top (13), the stopper plate (17) abuts the key top (13) to regulate the sidewise movement of the key top (13). | ||||||
