The present invention provides an adhesive composition, an adhesive sheet for batteries, and a lithium ion battery in which an adhesive is hardly eluted into an electrolytic solution even when the adhesive sheet is in contact with the electrolytic solution. The adhesive composition is used to form the adhesive layer (13) of the adhesive sheet (1) for batteries, which contains: (meth)acrylate polymer, the (meth)acrylate polymer contains carboxyl group in the molecule The monomer is used as the monomer unit of the polymer; and the metal chelate crosslinking agent. |
