ELECTRIC LEAKAGE DETECTOR

A first decision unit of an AC leakage detection section outputs a first output signal with a signal level depending on the level of a corrected first voltage signal output from a correction unit relative to a first threshold value. An excitation unit of a DC leakage detection section applies, to an excitation coil, an excitation voltage having an excitation frequency. A DC component detection unit outputs a second voltage signal representing magnitude of a DC component of the voltage obtained by a current-detecting resistor. A second decision unit outputs a second output signal having a voltage level depending on the level of the second voltage signal relative to a second threshold value. The DC leakage detection section includes a low-pass filter provided between an input terminal electrically connected to a connection point between the excitation coil and the current-detecting resistor and the excitation coil.
