    摘要: A battery with a laminated film as a casing encapsulating the battery power source is manufactured by the steps of: heat sealing the sealing area of the laminated film, whereby encapsulating the battery power source in the laminated film; and irradiating, with an electron beam, a portion of the heat sealed area, thereby the irradiated area crosses, in the direction along the peripheries of the heat sealed area, the overlapping areas of the heat sealed area and the leading electrodes projecting toward outside from the positive electrode and the negative electrode. According to this method, produced is a battery having a high peeling strength at the position of terminals of leading electrodes without sacrificing battery properties and therefore having high reliability and safety.
