A earth fault detector has a controller, a detection capacitor, a positive side first resistance connected to a positive side of a high voltage battery, a negative side first resistance connected to a negative side thereof, a positive side second resistance, a negative side second resistance, a positive side C contact switch, and a negative side C contact switch. The positive side C contact switch switches a connection destination of a first end of the detection capacitor to either a path including the positive side first resistance or a path including the positive side second resistance based on an instruction of the controller. The negative side C contact switch switches a connection destination of a second end thereof to either a path including the negative side first resistance or a path including the negative side second resistance based on an instruction of the controller.
