摘要： Provided is an input state detection device capable of reliably detecting contact and pressing of an object. A state switching switch (50) can switch a first state in which a voltage application terminal (21) of a constant-voltage power supply device (20, 220) is connected to a side of a first electrode (11) and a detection terminal (31, 231) of a detector (30, 230) is connected to a side of second electrodes (12a to 12h), and a second state in which the voltage application terminal (21, 221) of the constant-voltage power supply device (20, 220) is connected to the side of the second electrodes (12a to 12h) and the detection terminal (31, 231) of the detector (30, 230) is connected to the side of the first electrode (11). An input detector (70, 170, 270) 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 (12a to 12h) based on a value detected by the detector (30, 230) with the state switching switch (50) in the first state, and also detects whether the object is in the contact but not pressing state or in a pressing state with respect to the surface on the side of the second electrodes (12a to 12h) based on a value detected by the detector (30, 230) with the state switching switch (50) in the second state.
