PROBLEM TO BE SOLVED: To prevent corrosion of an electrode terminal caused by joining dissimilar metal in a terminal-to-terminal joint part of a battery pack. SOLUTION: This laminated battery 1 has a structure composed by sealing a stacked electrode comprising a positive electrode-side active electrode 2 and a negative electrode-side active electrode 3 with a laminate sheet 7. A positive electrode 30 integrally composed by coating a connection member joint part 22 of an electrical joint surface between a positive electrode-side terminal 4 and a connection member 6 with a coating resin 8 is electrically jointed to the electrode 2, and a negative electrode-side terminal 5 is electrically jointed to the electrode 3. In this battery pack using the laminated battery 1 as a unit cell, the connection member 6 of the electrode 30 of the laminated battery 1 is jointed to the terminal 5 of another laminated battery 1 by welding or the like. Since the connection member 6 is formed of the same material as that of the terminal 5, it is not necessary to seal them. COPYRIGHT: (C)2004,JPO&NCIPI
