Abstract
Provided is an input state detection device capable of reliably detecting contact and pressing of an object. A state switching switch can switch a first state in which a voltage application terminal of a constant-voltage power supply is connected to a side of a first electrode and a detection terminal of a detector is connected to a side of second electrodes, and a second state in which the voltage application terminal of the constant-voltage power supply is connected to the side of the second electrodes and the detection terminal of the detector is connected to the side of the first electrode. An input detector detects whether the object is in a non-contact state or in a contact but not pressing state with respect to a surface on the side of the second electrodes based on a value detected by the detector with the state switching switch in the first state.
