PURPOSE: A separator for the adhesive composition-supported battery, an electrode/separator-layered body containing the separator and an electrode/separator-adhered body containing a crosslinking adhesive composition are provided, to allow a battery to be assembled effectively and simply without the mutual separation of members and to improve the safety (no swelling) of a battery by improving the adhesion between an electrode and a separator. CONSTITUTION: The separator comprises a porous substrate; and a crosslinking adhesive composition comprising a polyfunctional isocyanate and a reactive polymer having a functional group capable of reacting with the isocyanate group of the polyfunctional isocyanate, supported on the porous substrate. Preferably the functional group capable of reacting with the isocyanate group is a carboxyl group or a hydroxyl group; and the reactive polymer contains at least one reactive monomer selected from the group consisting of a (meth)acrylate, a (meth)acrylic acid and a hydroxyalkyl (meth)acrylate, and has a glass transition temperature of 0-100 deg.C.
