PROBLEM TO BE SOLVED: To provide a keytop board capable of easily positioning a keytop in a rotation direction at the time of mounting of the keytop on a rubber elastic board. SOLUTION: The keytop board 1-1 is structured by mounting a keytop 10 on a rubber elastic board 50. A keytop positioning mechanism engaging the rubber elastic board 50 and the keytop 10 at only one point in the rotation direction is provided each at the keytop 10 and the rubber elastic board 50. The keytop positioning mechanism is constituted by engaging locking pieces 19, 21 protruded outward in a radial direction from an outer periphery face of a switch pressing part 17, and locking-piece engagement parts 55, 57 inserting the locking pieces 19, 21 continuously provided at an outer periphery of a switch-pressing part insertion part 53.
