PROBLEM TO BE SOLVED: To provide a battery capable of sufficiently showing a function for preventing adverse effects to the outside at the time of excessive temperature rise. SOLUTION: The battery has a PTC element (heat-sensitivity restriction element) 25 in a current conduction pathway from a battery power generation element 6 to a negative electrode terminal (output terminal) 2. Electric resistance of the PTC element 25 is rapidly increased at the time of excessive temperature rise, and output of current is blocked by restraining current conduction from the battery power generation element 6 to the negative electrode terminal 2. The battery has a bypass terminal 1 connected with the battery power generation element 6 without passing through the PTC element 25. High-voltage is applied to the battery power generation element 6 via the bypass terminal 1 without applying voltage to the PTC element 25 at a process of an inspection of insulation. The PTC element 25 does not receive any damage because high-voltage is not applied, and the battery can sufficiently show the function for preventing wrong influence to the outside by blocking the output of current at the time of excessive temperature rise.
