<p>A sealed battery is provided to prevent sputtered dust from being flowed to the inside of an electrode by welding a current collector to a core body at an electrode of a sealed battery, to reduce the generation of the internal short and to ensure high reliability. A sealed battery includes an electrode material(11) exposed with a cathode core body and an anode core body at both ends; a current collector(181) resistance-welded at both sides of a core body of one plural sheets; and a current collector accommodating component(183). The insulation sealing material is arranged at one side of the core body, the current collector and the current collector accommodating component.</p> |
