ELECTRICITY LEAKAGE DETECTION DEVICE

An object of the present invention is to provide an electric leakage detector with the ability to improve detection accuracy. A first decision unit (16) of an AC leakage detection section (1) outputs a first output signal with a signal level depending on whether a corrected first voltage signal output from a correction unit (14) is greater than, or equal to or less than, a first threshold value. An excitation unit (23) of a DC leakage detection section (2) applies, to an excitation coil (22), an excitation voltage having an excitation frequency. A DC component detection unit (25) outputs a second voltage signal representing magnitude of a DC component of the voltage obtained through conversion by a current-detecting resistor (24). A second decision unit (26) outputs a second output signal having a voltage level depending on whether the second voltage signal output from the DC component detection unit (25) is greater than, or equal to or less than, a second threshold value. The DC leakage detection section (2) includes a low-pass filter (27). The low-pass filter (27) is provided between an input terminal of the excitation unit (23) and the excitation coil (22). The input terminal is electrically connected to a connection point between the excitation coil (22) and the current-detecting resistor (24).
