Beschreibung
Zusammenfassung:	A resin-metal composite sealed container having a heat seal part using a heat-sealing resin, between an end part of a first metal foil and an end part of a second metal foil, and a metallically sealed part with a weld bead, on the end face outside the heat sealed part of the first metal foil and the second metal foil. The resin-metal composite sealed container, wherein the melting point of the metal constituting the metal foil is higher by 300°C or more than the thermal decomposition temperature of the heat-sealing resin, the specific gravity of the metal constituting the metal foil is 5 or more, and the weld bead is formed by a laser welding. A method for producing a metal-resin composite sealed container, comprising forming a container by heat sealing end parts of metal foils having laminated on at least one surface thereof a heat-sealing resin, and forming a metallically sealed part with a weld bead on the end faces of the metal foils by heating/welding an outer side of the heat sealed part of the container from a side of the end faces of the metal foils.
