The invention is concerned with a metal sheet covered with a polyester resin film having a biaxially oriented structure. The polyester resin film comprises an innermost layer of polyester resin which is directly in contact with the metal sheet surface or indirectly in contact therewith by laying a thermosetting resin layer between the polyester resin film and the metal sheet, and which has a planar orientation coefficient of 0.000 to 0.100, and an outermost layer of polyester resin having a planar orientation coefficient of 0.010 to 0.150. Such a metal sheet covered with a polyester resin film is suitable for applications in which excellent formability and excellent corrosion resistance after severe forming are required, especially for drawn and stretch formed cans having high can height.
