摘要
A method of forming a metal sheet into a target shape by press-forming, such that the metal sheet is formed into an intermediate shape that is different from the target shape and then the target shape is formed from the intermediate shape, the method includes: when forming the intermediate shape from the metal sheet, forming the intermediate shape by forming a first region including at least a portion at which a ratio of sheet thickness reduction from the metal sheet is larger when the target shape is formed via the intermediate shape than when the target shape is formed directly from the metal sheet.
