A plurality of cooling air passages 132 extended penetrating the film packaging body in a completion state of the battery are formed in the passage formation member 130. A sectional shape of each battery element is formed into a corrugated shape. A corrugated part having the same shape of the corrugated shape of the battery element is formed in the film packaging body along an outer circumferential surface of the battery element. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
