In a state where the hemming structure is formed, an opposite surface 3a of the flange portion 3 to a main surface 2a of the body part 2 is provided with grooves 10 that are formed along a direction crossing the folding line 4. Further, in the case where the metal panel 1 is cut in a direction orthogonal to an extending direction of the grooves 10, a cross sectional shape of the groove 10 is a channel shape, a V shape or a U shape.SELECTED DRAWING: Figure 4
