Patent ID: 8264463

Claim:
An input device that inputs information by a slide operation depending on an operation body, the input device comprising: a housing having an operation surface; a detection unit that is provided in the housing and includes an electrostatic capacitance sheet member which detects a slide position of the operation body to output a position detection signal; and an operation unit that covers an entire surface of the detection unit and is slide-operated along the operation surface of the housing, wherein the operation unit has a concave shape formed by being dug-down along a sliding direction from one portion of the operation surface of the housing and also, by being dug-up toward the other portion of the operation surface thereof, and wherein the electrostatic capacitance sheet member includes a switch portion that is switched by a press-in operation of the operation body to the operation unit; and wherein the electrostatic capacitance sheet member includes a sheet shaped detection electrode which detects the slide position of the operation body and outputs the position detection signal, wherein a portion of the detection electrode protuberates in a dome shape, and wherein a dome-shape-protuberating region of the detection electrode forms a movable contact constituting the switch portion.
