    Abstract: Provided is a spouted pouch, said pouch being suitable for achieving a high gas-barrier property. This pouch X is provided with a pouch main body 10 and a spout 20. The pouch main body 10 is configured from a film having a sealant layer on an inner surface thereof. The spout 20 is an integrally molded resin body and contains each of an olefin-based resin and an ethylene-vinyl alcohol copolymer and is attached to the pouch main body by thermal welding with the sealant layer.
