Beschreibung
Zusammenfassung:	A can lid made of a resin laminate steel sheet for a resin-metal composite container, includes: a top sheet portion; and a curved portion located at an outer periphery of the top sheet portion, in which the resin laminate steel sheet includes a steel sheet, a thermoplastic polyester-based resin layer provided at a first surface of the steel sheet, a modified polypropylene-based resin layer provided at a second surface of the steel sheet, a polypropylene-based resin layer, and an ethylene-propylene copolymer resin layer, a melting point of the ethylene-propylene copolymer resin layer is 135°C or higher and 150°C or lower, a melting point of the thermoplastic polyester-based resin layer is higher than a melting point of the polypropylene-based resin layer by 40°C or more, and a range of a proportion of the ethylene component in the ethylene-propylene copolymer in the ethylene-propylene copolymer resin layer is 1.0 mass% or more and 45.0 mass% or less.
