Abstract: This structural component is formed from a steel sheet, and has a flat sheet part 10a and a bent part 10b. The bent part 10b satisfies the following formula (1) and formula (2). (1): 25=varea=40 (2): 0.17=r/t=6.90 Wherein, varea represents the square root [µm] of a projection area of a minute defect on the bending inner side of the bending part 10b, r represents the minimum value [mm] of the curvature radius on the bending inner side of the bending part 10b, and t represents the sheet thickness [mm] of the flat sheet part 10a.
