  "textContent": "A laminated body includes a barrier layer made of metal, a base material layer made of a heat-resistant resin laminated on an outer side surface of the barrier layer, and a sealant layer made of a heat sealable resin laminated to an inner side surface of the barrier layer. The base material layer includes a polyester film layer as an outer layer and a polyamide film layer as an inner layer. The polyester film layer is 500 MPa to 600 MPa in a sum of breaking strength in an MD and breaking strength in a TD, 0.8 to 1.1 in a ratio of the breaking strength in the TD to the breaking strength in the MD, and 110% to 200% in breaking elongation in the MD and breaking elongation in the TD. The MD denotes a machine flow direction, and the TD denotes a direction perpendicular to the MD.",
