PROBLEM TO BE SOLVED: To provide a switch device in which variations in a shape and a projected volume of pushing operation portions provided in an elastic adhesive sheet can be reduced. SOLUTION: The switch device 2 includes a base board 3, a fixed contact 4 provided on the base board 3, a movable contact 6 which is deformed elastically to contact with the fixed contact 4 by a pushing operation, and a flexible adhesive sheet 7 which is fixed by adhesion on the base board 3 covering the movable contact 6 and holds the movable contact 6 by adhesion. In a portion of the flexible adhesive sheet 7 where a central portion of the movable contact 6 overlaps, there is provided a pushing operation portion 8 projecting in a direction parting with the movable contact 6. The pushing operation portion 8 includes a ring-shaped projected portion 8a projecting in a direction parting with the movable contact 6 and a plate portion 8b connected through with the ring-shaped projected portion 8a. The ring-shaped projected portion 8a and the plate portion 8b are formed of the flexible adhesive sheets 7 which is plastic-deformed by a press molding. COPYRIGHT: (C)2009,JPO&INPIT
