PROBLEM TO BE SOLVED: To provide a chattering elimination circuit capable of improving the response of an output signal to a change of an input signal with a low cost and simple configuration.SOLUTION: A chattering elimination circuit (30) for eliminating chattering included in an input signal from an input terminal (fin) and outputting a signal from which chattering has been eliminated from an output terminal (fout), includes: a filter circuit (30a) composed of a resistor (31) and a capacitor (32); and a discharge circuit (30b) which is provided separately from the filter circuit and discharges the charge accumulated in the capacitor of the filter circuit.SELECTED DRAWING: Figure 1
