A switch monitoring circuit (1) has an external input terminal (10) connected to a switch, a voltage applying unit (30) that applies a driving voltage to the external input terminal (10), a voltage detecting unit (40) that detects a change in the voltage at the external input terminal (10), a control unit (50) connected to the voltage applying unit (30) and voltage detecting unit (40), and a charge storage unit (20) connected to the external input terminal (10) and voltage applying unit (30). The charge storage unit (20) has a voltage applying terminal (21) to which the driving voltage is applied, a first resistive element (22), one of the terminals of which is connected to the external input terminal (10) and the other of the terminals of which is connected to the voltage applying terminal (21), and a capacitive element (23), one of the terminals of which is connected to the voltage applying terminal (21) and the other of the terminals of which is grounded. The capacitive element (23) performs charging from the voltage applying terminal (21) and discharging to the voltage applying terminal (21).
