A current leakage detection device includes a first voltage-dividing circuit, a second voltage-dividing circuit, a switching unit, and a controller configured to detect current leakage. The controller performs: a first input step of switching the second voltage-dividing circuit to the current-carrying state and inputting a first divided voltage value from the first voltage-dividing circuit and a second divided voltage value from the second voltage-dividing circuit; a second input step of switching the second voltage-dividing circuit to the current-blocked state and inputting a third divided voltage value from the first voltage-dividing circuit; a characteristic determination step of determining whether there is an abnormality in the first voltage-dividing circuit and the second voltage-dividing circuit based on the first divided voltage value and the second divided voltage value; and a current leakage detection step of detecting the current leakage based on the first divided voltage value and the third divided voltage value.
