Abstract
A blank sheet which is a material for an outer plate component for an automobile includes a steel sheet. A rolling direction of the steel sheet extends along a longitudinal direction of the blank sheet, and a thickness is 0.6 mm or less. The steel sheet may have a chemical composition in which arithmetic average waviness Wa is 0.10 to 0.30 μm. The steel sheet may have a chemical composition in which ΔC calculated from Cthat is a C content at a depth position of 20 μm from a surface, Cthat is a C content at a depth position of 60 μm from the surface, and Expression (1) is 0.20 to 0.90 mass %/mm, and a tensile strength is 500 MPa or greater,ΔC=(C−C)/(0.04) (1).
