<p>A laminated metal sheet according to the present invention includes a metal sheet; a first polyester resin layer formed on a surface of the metal sheet, the surface forming an outer face side of a container; and a second polyester resin layer formed on a surface of the metal sheet, the surface forming an inner face side of the container. The first polyester resin layer contains polyethylene terephthalate or a copolymerized polyethylene terephthalate with a content of a copolymerized component of less than 6 mol% in a ratio of 30% by mass or more and 60% by mass or less, polybutylene terephthalate or a copolymerized polybutylene terephthalate with a content of a copolymerized component of less than 5 mol% in a ratio of 40% by mass or more and 70% by mass or less, and a polyolefinic wax in an amount of 0.01% or more and 3.0% or less in outer percentage. The second polyester resin layer is a copolymerized polyethylene terephthalate with a content of a copolymerized component of less than 22 mol%. Residual degrees of orientation of the first and the second polyester resin layers are less than 30%.</p> |
