Zusammenfassung:	PROBLEM TO BE SOLVED: To realize the improvement of dent resistance of part of a vehicle panel while suppressing cost increase.SOLUTION: A vehicle panel manufacturing method according to one embodiment of the present invention is for manufacturing a vehicle panel 1 having a reinforced region A, the dent resistance of which has been improved, and the reinforced region A, the dent resistance of which has been formed by engraving a Peano curve Z1, a Sierpinski gasket Z2, a Sierpinski carpet Z3 or the like, which is a fractal graphic Z, the fractal dimensionality of which is greater than 1, by incremental forming.SELECTED DRAWING: Figure 9 【課題】コストアップを抑えつつ、車両用パネルにおける部分的な耐デント性の向上を実現する。【解決手段】本発明の一実施形態に係る車両用パネルの製造方法は、耐デント性の向上が図られた部位である強化部位Ａを有する車両用パネル１の製造方法であって、耐デント性の向上が図られた強化部位Ａは、インクリメンタル成形によって、フラクタル次元が１を超えるフラクタル図形Ｚであるペアノ曲線Ｚ１やシェルピンスキー・ギャスケットＺ２やシェルピンスキー・カーペットＺ３等を刻設することにより形成される。【選択図】図９
