Abstract
In a manufacturing method of a sealed battery, a positive terminal is provided on one end portion of a lid and a negative terminal is provided on another end portion of the lid. An end surface on the positive terminal side of the lid is inserted into an opening, and made to contact an inside wall of the opening. Then, an end surface on the negative terminal side of the lid is inserted into the opening, and the battery can and the lid are welded together. Therefore, even if metal foreign bodies get into the battery can at the time of manufacture, they will get in on the negative terminal side, so a decrease in voltage of the sealed battery is able to be suppressed.
