PROBLEM TO BE SOLVED: To provide a resin-coated steel sheet which is obtained by coating both sides of a steel sheet with a resin film, and can prevent the occurrence of hair in the forming of a shear spun can, and to provide the shear spun can obtained by using the steel sheet.
SOLUTION: On the forming of the shear spun can from a resin-coated steel sheet, the steel components and material of the steel sheet used as an original sheet are controlled, and the face strength ratios in the crystal faces are controlled. Thus, a steel sheet thinner than the conventional one is used, and the increase of the thickness of the steel sheet in the upper end part of the can wall on drawing is suppressed, and the substantial ironing quantity in an ironing stage which is the main stage where hair occurs is reduced. Simultaneously with this, the working hardening of the steel sheet in the process of the working is suppressed, and the increase of the deformation resistance thereof is prevented. Further, surface treatment such as electrolytic chromate treatment is performed, and the surface thereof is coated with a non-oriented polyester resin film which can withstand severe working.
