1. An adhesive resin composition consisting essentially of:
an acid-modified polyolefin resin component (A) having a weight average molecular weight of 30,000 or more and 150,000 or less;
a resin component (B) having an epoxy group in a molecule;
a resin component (C) having an amino group at a molecular end;
an isocyanate compound (D); and
a solvent (S),
wherein
a content of said resin component (B) is 1 part by mass or more and 30 parts by mass or less based on 100 parts by mass of said acid-modified polyolefin resin component (A),
a content of said resin component (C) is 6 parts by mass or more and 15parts by mass or less based on 100 parts by mass of said acid-modified polyolefin resin component (A),
said acid-modified polyolefin resin component (A) is polyethylene, polypropylene, poly-1-butene, or polyisobutylene which is modified with an unsaturated carboxylic acid or a derivative thereof selected from the group consisting of maleic anhydride, itaconic anhydride, citraconic anhydride, nadic anhydride, methyl acrylate, methyl methacrylate, ethyl acrylate, butyl acrylate, maleic acid monoethyl ester, acrylamide, maleic acid monoamide, maleimide, N-butylmaleimide, sodium acrylate, and sodium methacrylate,
said acid-modified polyolefin resin component (A) does not comprise a copolymer of propylene and an olefin-based monomer, and
said resin component (C) is at least one selected from the group consisting of diethylenetriamine, triethylenetetramine, tetraethylenepentamine, an amine-modified hydrogenated styrene-based thermoplastic elastomer in which a molecular end is modified with an amino group, polyethyleneimine, nylon 6, nylon 66, and nylon 12,
wherein the adhesive resin composition is used in the interior of outer packages of batteries.
