Input device
First Claim
1. An input device comprising:
- an insulating thin film substrate on which a fixed electrode that includes a capacitance detection electrode, peripheral stationary sections, and a connection section is formed, and a movable electrode formed of a conductive material, the movable electrode including a displacement section that is disposed on a first surface of the thin film substrate opposite to a second surface on which the capacitance detection electrode is formed so as to be opposite to the capacitance detection electrode, and deformed by a pressing force in a direction of the capacitance detection electrode; and
a stationary section that is connected to the connection section of the fixed electrode,the input device detecting a change in capacitance that occurs when the displacement section has been pressed, andthe thin film substrate functioning as an insulating layer that prevents the displacement section from being electrically connected to the capacitance detection electrode even if the displacement section has been deformed,wherein the peripheral stationary sections and the connection section of the fixed electrode are disposed on the first surface of thin film substrate.

Abstract
An input device includes a thin film substrate on which a fixed electrode is formed, and a movable electrode formed of a conductive material, the fixed electrode including a capacitance detection electrode and a connection section, the movable electrode including a displacement section that is disposed to be opposite to the capacitance detection electrode and deformed by a pressing force, and a stationary section that is connected to the connection section, the input device detecting a change in capacitance that occurs when the displacement section has been pressed. The input device has a reduced thickness, and can be inexpensively produced by reducing the number of parts. Moreover, the input device can be easily incorporated in an electronic instrument.
