Beschreibung
Zusammenfassung:	The invention provides a packaging material that has high formability and that does not undergo a decrease in the adhesion strength between layers and appearance defects such as lifting between layers even after thermal fusion between portions of the sealant layer performed for sealing battery elements and furthermore after a long-term durability test under high temperature and high humidity. The adhesive for the packaging material including, as essential components, a polyol composition (A) and a polyisocyanate composition (B), wherein the polyol composition (A) includes a polyester polyol made from, as essential materials, a polybasic acid or its derivative and a polyhydric alcohol, the polybasic acid or its derivative material is all an aromatic-ring-containing polybasic acid or its derivative, and the polyester polyol has a number-average molecular weight in a range of 3000 to 100000; a battery packaging material, a battery container, and a battery that use the adhesive.
