Abstract
A short circuit detection device for detecting a short circuit occurring in a detection target measures an electrostatic capacitance value of the detection target and determines, on the basis of the measured electrostatic capacitance value, a current value of a current to be supplied to the detection target. Furthermore, the short circuit detection device supplies the current having the determined current value to the detection target and detects a short circuit in the detection target while the current is being supplied to the detection target.
