摘要：
A method for bending a sheet metal comprises: a hardness adjustment process wherein a blank (10), including a high-hardness region (11) and a low-hardness region (12) having a lower hardness than the high hardness region (11), is formed by changing the hardness of at least a part of a sheet metal; and a bending process wherein a product (20) is formed by bending low-hardness region (12) of blank (10).
