PROBLEM TO BE SOLVED: To electrically connect a conductive member including a poly-switch with a positive electrode by spot welding without increasing a total height of batteries with positive electrodes with smaller heights. SOLUTION: The conductive plate to be spot welded with a positive electrode of a battery is narrowed toward inside into a concave shape, so that those positive electrodes with smaller heights can be spot welded.
