Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a voltage detection circuit of a battery that can accurately detect each voltage of the battery such as a size X battery. SOLUTION: A first input switching means 22 where the positive and negative electrodes of each battery are connected each other and the positive or negative electrode of a selected battery is selected for reading voltage, a second input switching means 24 where the positive and negative electrodes of each battery are connected each other and either the positive or negative electrode of the selected battery is selected for reading voltage, a voltage detection means 30 for obtaining the detection output voltage of the battery according to an output voltage from the first input switching means 22 and that from the second input switching means 24, and a processing means 40 for individually outputting the voltage of each battery by converting the detection output voltage of the battery from the voltage detection means 30 from analog to digital and performing an operation are provided.
