In a method for manufacturing a packed electrode, an electrode is set between two separation layers that are made of resin, a heat-resistant layer is set between at least one of the two separation layers and the electrode, the two separation layers, the electrode and the heat-resistant layer, an overlapped portion of the two separation layers overlapped with the heat-resistant layer interposed therebetween is pinched, pressed and heated by a pair of heat sealing chips at an outside of the electrode, and the two separation layers are fastened by destroying the heat-resistant layer at the overlapped portion that are pressed and heated. According to the above manufacturing method, man-hours required for stacking can be reduced by integrating the heat-resistant layer with the packed electrode.
