PROBLEM TO BE SOLVED: To provide a packaging material for an electrochemical cell, in which adhesive strength of a heat seal part is maintained even under high temperature conditions to exhibit certain safety performance.SOLUTION: The packaging material for an electrochemical cell is configured by sequentially laminating at least a base material layer 111, a metal foil layer 112, an acid-modified polyolefin layer 114, and a polyolefin layer 115. The polyolefin layer 115 is configured by adding a propylene-based elastomer resin with a melting point higher than 150°C to a polypropylene resin. |
