In-vehicle input device

An on-vehicle input device comprising:

• a touch panel including:
• a lower electrode;
• an upper electrode facing the lower electrode;
• an operation surface located above the upper electrode, the operation surface including a plurality of operation areas;
• a spacer disposed between the lower electrode and the upper electrode, the spacer having a plurality of openings disposed under the operation areas such that the operation areas are superimposed on the corresponding operation areas in plan view;
• and
• a first suppression layer disposed between the operation surface and the upper electrode, or disposed on an upper surface of the operation surface, the first suppression layer being made of a conductive metal to be a first shield eliminating or reducing formation of a capacitance between the upper electrode and an operator;
• and
• a second suppression layer disposed below the lower electrode on a side opposite to the upper electrode, the second suppression layer being made of a conductive metal to be a second shield eliminating or reducing formation of a capacitance between the lower electrode and the operator,
• wherein the device is configured to detect an input operation by an operator, based on a change in a distance between the lower electrode and the upper electrode in the openings in response to the operator's pressing any of the operation areas.
