Claim 3:
4. The earth leakage detection device according to claim 1, wherein
the earth leakage detection device includes a terminal of the third resistor configured to be applied a first fixed potential and a second fixed potential, the first fixed potential being set to an upper limit potential of a measurement range of the voltage measurement unit, and the second fixed potential being set to a lower limit potential, the terminal of the third resister not being connected to the second resistor, and
the earth leakage determination unit applies the second fixed potential to the terminal when a measured voltage sticks to an upper limit of the measurement range, and applies the first fixed potential to the terminal when the measured voltage sticks to a lower limit of the measurement range.
