PROBLEM TO BE SOLVED: To provide a key sheet which gives a sense of stability, and in which, even if a key top is operated so as to be shifted sidewise, excessive changes, such as large staggering of the key top or overlapping of key tops each other, will not be caused. SOLUTION: This key sheet 10 includes 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, and 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, and abuts against the key top 13 in sidewise movement of the key top 13 and regulates the sidewise movement of the key top 13.
