High production stability is obtained when a laminate is produced by bonding to a base fabric, and the production can be performed with less labor and cost. A multilayer film used by being bonded to a base fabric, comprising: an adhesive layer on a side bonded to the base fabric; and an airtight layer bonded to the adhesive layer; The layer and the hermetic layer include a thermoplastic polyester elastomer, and the melting point of the hermetic layer is higher than the melting point of the adhesive layer.
