IN-VEHICLE INPUT DEVICE

An in-vehicle input device (100) includes a touch panel (10) including a lower electrode (11a), an upper electrode (13a), and a spacer (12), and is capable of detecting a capacitance (C0) between the lower electrode and the upper electrode. The device has an operation surface (15a) located above the upper electrode. The operation surface includes a plurality of operation areas (15b). The spacer has a plurality of openings (12a) that coincide with the operation areas in plan view. The device further includes a suppression layer (14) that is disposed between the operation surface and the upper electrode or disposed on an upper surface of the operation surface. The suppression layer eliminates or reduces formation of a capacitance between the upper electrode and an operator. The device detects an input operation based on a change in distance between the lower electrode and the upper electrode in response to pressing any of the operation areas by the operator.
