<P>PROBLEM TO BE SOLVED: To provide a secondary battery that can improve the space efficiency of sheet-like positive electrodes and sheet-like negative electrodes, and can also securely prevent the excessive temperature rising of the electrodes. <P>SOLUTION: Laminated cells 16, which are formed by a plurality of sheet-like negative electrodes 14 and a plurality of sheet like positive electrodes 15 being alternately laminated with separators interposing between them, are housed in a unit part 12. The laminated cells 16 are folded back to form a U-shape. At a concave part 21 of the U-shaped laminated cells 16, in which faces 161 oppose each other with a space between them, a pair of insulating flat plates 22 and 23 and a heat transfer member 24 in a corrugated plate shape which is arranged between and connected to the two flat plates 22 and 23 are disposed. Both right and left ends of the heat transfer member 24 are connected to side walls 121 and 122 of the unit part 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
