Disclosed are a bipolar battery, a bipolar battery component and a method of manufacturing the same. The bipolar battery minimizes the occurrence of gas bubbles to provide superior battery performance. A battery element has a plurality of bipolar electrodes stacked upon one another while interposing separators therebetween. The bipolar electrode includes a collector formed with a cathode on one surface and an anode on the other surface. The component is a charging part with charging material disposed between collectors and separators to surround at least a periphery of the cathode and a periphery of the anode. An exhaust part is mounted to the charging part to exhaust a residual gas bubble from an inner space to outside of the inner space when stacking the bipolar electrodes.

A laminate battery is provided with a tab, an electric power generating element connected to the tab, and a laminate sheet allowing the electric power generating element to be accommodated. The laminate sheet includes a metallic layer and a thermally welding resin layer laminated on the metallic layer. The tab and the thermally welding resin layer are welded by permitting a thermally welding area, which is formed in at least one of the thermally welding resin layer and the tab, and the other of the thermally welding resin layer and the tab to be welded to one another.
