A touch sensor switch for easily taking out an output of a touch sensor with high reliability. Push-type switching elements 2 A, 2 B, and 2 C are mounted on a printed circuit board 1 , a rubber dome 3 is provided with expanded portions 30 A, 30 B, and 30 C for housing the switching elements 2 A, 2 B, and 2 C, the switching elements 2 A, 2 B, and 2 C are provided with conductive films 41 A, 41 B, and 41 C on an outer surface and a lower face, conductive parts 31 A, 31 B, and 31 C are provided at a conductive part such as an upper surface of the expanded portions 30 A, 30 B, and 30 C of the rubber dome 3 , or a wiring pattern of the printed circuit board 1 , and the conductive films 41 A, 41 B, and 41 C contact with the conductive parts 31 A, 31 B, and 31 C constantly by a biasing force of the switching elements 2 A, 2 B, and 2 C regardless the operation of switch knobs 4 A, 4 B, and 4 C.
