Abstract
A key top of a key switch is formed so as to extend in a horizontal direction, not in a vertical direction. On a rear surface of the key top, a reinforcing member that horizontally extends is mounted on one end portion in the vertical direction and a torsion bar that horizontally extends is rotatably supported on the other end portion in the vertical direction. When the key top is pressed against a biasing force of an elastic member, the reinforcing member prevents the key top from deforming.
