PROBLEM TO BE SOLVED: To constitute a switch operating mechanism with a small number of part items and reduce the thickness thereof by providing a substrate having a membrane switch arranged thereon and an operation panel arranged opposite to the substrate to form a two-layer structure, and forming a switch operation part on a part of the operation panel in such a manner as to be deformable by pressing. SOLUTION: An operation panel 20 is formed by laminating a thin decorative resin film 20A for the surface and a hard resin panel 20B for the lower layer, and a switch operation part 22 is elastically supported on the resin panel 20B. The switch operation part 22 is basically formed of only the layer of the resin panel 20B, and a boss 23 is raised on the back surface of the switch operation part 22 so as to point a membrane switch 30. The switch 30 is mounted on a flexible wiring board 31, and a support substrate 32 supports the wiring board 31. The boss 23 is separated from the switch 30 in the state where no pressing force is added to the operation part 22, and when a pressing force is added, the boss 23 is lowered to energize the switch 30.
