PROBLEM TO BE SOLVED: To provide a packaging material for an electrochemical cell, excellent in durability and hardly causing delamination.SOLUTION: A base material layer 112 includes a polyester-based resin layer 112a disposed on the external side and a polyamide-based resin layer 112b disposed on the barrier layer 114 side. An adhesion layer 113 comprises at least one resin selected from among copolymer polyamide, acid-modified polyolefin, metal-modified polyolefin, a mixed resin of copolymer polyamide and acid-modified polyolefin, a mixed resin of copolymer polyamide and metal-modified polyolefin, a mixed resin of copolymer polyamide and polyester, polyester, a mixed resin of polyester and acid-modified polyolefin, and a mixed resin of polyester and metal-modified polyolefin. |
