Classification: CPC G  H | IPC G  H

Claim 0:
1. An input device configured to be operated by an operation body, the input device comprising:
a detection surface configured to be operated by the operation body;
a first fixed electrode;
a movable electrode having a lower surface facing an upper surface of the first fixed electrode and being capacitively coupled to the first fixed electrode, the movable contact being displaceable to approach the first fixed electrode in response to a pressing of the detection surface by the operation body;
a first terminal configured to be connected to an outside of the input device and to output to the outside of the input device, a first electric signal containing a change in a capacitance between the first fixed electrode and the movable electrode;
a second terminal configured to be connected to the outside of the input device and to output, from the movable electrode to the outside of the input device, a second electric signal containing a change in a capacitance between the operation body and the movable electrode; and
a direct-connection line electrically connecting the movable electrode to the second terminal via no capacitor.
