Abstract: An inversion plate short-circuits the positive electrode external terminal and the negative electrode external terminal to each other by changing its position. A temperature sensitive member is disposed adjacent to the inversion plate on the side opposite to a direction in which the inversion plate changes its position. The volume of temperature sensitive member increases due to a rise in temperature. The temperature sensitive member contains aluminum phosphite and calcium carbonate.
