Abstract
An electrostatic capacitance detection device includes a plurality of electrodes configured to detect an electrostatic capacitance, an electrostatic capacitance measurement part configured to select one electrode from the plurality of electrodes as a detection electrode, to allow the electrodes other than the detection electrode to be in a first electric potential condition and then to be in a second electric potential condition that is different from the first electric potential condition, and to measure a first voltage of the detection electrode in the first electric potential condition and a second voltage of the detection electrode in the second electric potential condition, and a judgment part configured to compare measurement values based on the first and the second voltages of the detection electrode, thereby to judge whether the detection electrode is in a short circuit condition.
