Patent ID: 8669502

Claim:
An operation device comprising: an operation region on a top plate made of a material having an electric insulating property; an electrode terminal portion which is arranged just below the operation region, and serves as an electrostatic capacity type touch switch; a guide holder which slidably holds the electrode terminal portion; and an operation substrate which is provided with the guide holder, wherein the electrode terminal portion has: a detection portion which comes into close contact with a back surface of the operation region, a spring portion which has an elastic force pressing the detection portion to the back surface of the operation region, and a slide portion which is movably retained in the guide holder, moves together with the detection portion due to the elastic force of the spring portion, and presses the detection portion to the back surface of the operation region, and wherein the detection portion, the spring portion and the slide portion are integrally formed, and a change of an electrostatic capacity in the electrode terminal portion is configured to be output as an operation signal.
