PROBLEM TO BE SOLVED: To improve moldability without decreasing rigidity of a reinforcement bead in a vehicle body panel press-molded from a metal plate blank.SOLUTION: A vehicle body panel (2) is press-molded from a metal plate blank (20). A plurality of rows of reinforcement beads (3) are formed almost in parallel with intervals. In the plurality of rows of reinforcement beads (3), radii of curvature of corner parts (3a and 3b) of the reinforcement beads (32 and 31) positioned on a central side with respect to the reinforcement bead (33) positioned on the edge end side of the blank are increased in a gradual or stepwise manner. |
