To impart a desired click feel even if there is no spacer by forming the recessed parts around the pressing part of a click dome sheet having one or more pressing parts protruding in dome shape.
In a click dome sheet 1, the pressing part 12, the recessed part 13 and the disconnecting part 14 are formed by heat press molding on a sheet composed of a synthetic resin such as polyethylene terephthalate(PET). The recessed part 13 is formed so as to project to the switch board 2 side on the opposite side in the protruding direction of the pressing 12. The recessed part 13 does not surround the whole periphery to a single pressing part 12, but is disconnected in at least one place. This disconnecting part 14 corresponds to air vent clearance when pushing the pressing part 12. Thus, since there is no need to use a separate spacer, the material cost, the manufacturing mold cost and the assembling cost of a spacer can be reduced.
