The coated layer comprises a mixture whose main constituents are a polyester resin and a melamine compound, and not less than 60% by weight of constituents forming the coated layer is the polyester resin. Additionally or alternatively, the coated layer has carboxylic acid and primary groups such that, at a surface thereof, the concentration of the carboxylic acid groups is not less than 0.005 and the concentration of the primary amine groups is not less than 0.0015.
