<P>PROBLEM TO BE SOLVED: To provide a heat-sensitive adhesive sheet capable of keeping good adhesiveness with an adherend even when brought into contact with an electrolytic solution for suitably sealing the electrolytic solution. <P>SOLUTION: The heat-sensitive adhesive sheet is formed of an adhesive composition containing an olefin-glycidyl(meth)acrylate copolymer with weight-average molecular weight of 10,000-500,000 as a principal component, and a content of a low molecular weight component with molecular weight of ≤5,000 in the olefin-glycidyl(meth)acrylate copolymer is ≤20 wt%. Using the heat-sensitive adhesive sheet, firm adhesiveness to a polyimide film and excellent electrolytic solution resistance can be achieved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
