A battery, which is provided with a pressure-type current interrupt mechanism, is provided with: a gas-generating material placed outside an electrode body and within a battery case; a positive electrode potential member that is placed outside the electrode body and within the battery case in a manner contacting the gas-generating material, and conducts with the positive electrode of the electrode body; and a negative electrode potential member that is placed outside the electrode body and within the battery case in a manner contacting the gas-generating material while being spaced from the positive electrode potential member, and conducts with the negative electrode of the electrode body. The gas-generating material includes a gas-generating agent that generates a gas when the potential of the positive electrode potential member exceeds a gas generation potential. |
