Abstract
[SUMMARY] [PROBLEM] To further improve punch-withdrawing performance while maintaining ironing formability during DI forming. [SOLUTION] A film-laminated steel sheet according to the present invention includes: a steel sheet serving as a base material; film layers formed by thermoplastic polyester films provided on front and rear surfaces of the steel sheet; and wax layers provided on the film layers, wherein a coating weight of the wax layer is within a range of 0.030 to 0.135 g/m<2> per side, the coating weights of the wax layers are different between the front surface and rear surface of the steel sheet, and a coating weight ratio, which is obtained by dividing the coating weight of the wax layer on a side with a higher coating weight by the coating weight of the wax layer on a side with a lower coating weight, is within a range of 1.05 to 1.35.
