1. A cell voltage detection device comprising:

  • a voltage detection element for detecting voltages of cells within a cell block formed with a plurality of cells serially connected to each other; and

    another voltage detection element for detecting a voltage of an operating power source of the voltage detection element,wherein the operating power source of said voltage detection element is supplied from a voltage of the inside or both ends of said cell block,wherein an operating power source of said another voltage detection element is supplied from a power source outside of said cell block,the operating power source of said another voltage detection element being less variable than the operating power source of said voltage detection element.
