<P>PROBLEM TO BE SOLVED: To provide a lithium secondary battery which improves not only water resistance, but also rigidity and vibration resistance. <P>SOLUTION: A positive electrode layer (13) and a negative electrode layer (16) of a battery element (20) are stacked through a polymer electrolyte layer (18) therebetween on an electricity collecting body (12). Between the battery element (20) and a packaging material (22) which hermetically encloses the battery element, sheet-like moisture absorbing materials (24) are disposed parallel to the electricity collecting body. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
