PROBLEM TO BE SOLVED: To provide a sheet key capable of expressing a difference in shape of keys by changing only a sheet while clearly expressing the shape of a key when the shape of the key is to be changed due to a difference in specifications between the keys. SOLUTION: A key member 1 is manufactured in an emboss shape formed by separating a disk-like key top part 2 from a peripheral portion 4 at annular groove parts 3. A circular key top is formed by forming a circular recessed groove 7 in the sheet 6 and fitting the recessed groove 7 into the groove part 3 of the key member 1. For a square key top, a square protruded line 8 is formed on the sheet 6 so as to be disposed on the inside of the groove part 3 so that the protruded line 8 can ride on the key member 1 on the inside of the groove 3. Thus the shape of the key top can be clearly distinguished by the recessed groove 7 and the protruded line 8.
