Summary:PURPOSE: An insulation resistance measurement circuit is provided to measure insulation resistance by autonomously inspecting an insulation resistance sensing part without the leaked current generation. CONSTITUTION: A first source resistance(103) is connected to a plus terminal of an insulation resistance measurement battery, and a second source resistance(104). The second source resistance is connected to a minus terminal of the insulation resistance measurement battery, and the first source resistance. A first operational amplifier(105) senses voltage of the first source resistance by using first voltage. A second operational amplifier(106) senses voltage of the second source resistance by suing second voltage. A first switch(107) is connected to the plus terminal of the insulation resistance measurement battery, and the first source resistance.
