1. A can obtained by press-forming a resin-coated steel plate obtained by providing, on at least one surface of the steel plate, (i-1) an alloy layer of iron and at least one metal selected from tin, zinc and nickel, wherein when the alloy layer contains tin, the content of tin is in a range of larger than 0.05 g/m2 but is smaller than 1.5 g/m2, when the alloy layer contains zinc, the content of zinc is larger than 0.03 g/m2 but is smaller than 1.8 g/m2, and when the alloy layer contains nickel, the content of nickel is larger than 0.03 g/m2 but is smaller than 1.8 g/m2, or (i-2) a tin-plated layer containing tin in an amount of 0.5 g/m2 to 12 g/m2, (ii) a silane coupling agent-treated layer, and (iii) a copolymerized resin layer of a polyethylene terephthalate in this order from the side of the steel plate.
