An insulation resistance measuring device as an insulation resistance measuring device between a battery including a plurality of battery cells and a ground includes: a first voltage distribution unit, which distributes a voltage between the positive electrode of the battery and the ground; a second voltage distribution unit, which distributes a voltage between the negative electrode of the battery and the ground; a first switch SW1 connecting the positive electrode of the battery and the first voltage distribution unit; and a second switch SW2 connecting the negative electrode of the battery and the second voltage distribution unit, wherein when the first voltage, which is an output of the first voltage distribution unit, is saturated during the on-period of the first switch SW1, or the second voltage, which is an output of the second voltage distribution unit, is saturated during the on-period of the second switch SW2, the current switching cycle of the first and second switch from the previous switching cycle is reduced.
