This invention provides a method for manufacturing stamped parts that can be applied even when manufacturing stamped part shapes that cannot be formed without significant deep drawing. When a sheet metal is stamped into a final part shape through two or more stamping processes including a stamping step, the amount of material flow required to form the final part shape is calculated based on the increase in the cross-sectional length of the final part shape relative to the initial shape when the sheet metal is stamped into the final part shape in a single stamping step. This calculated amount of material flow is allocated to each process including the final stamping step, and the pre-formed shape after stamping in processes other than the final stamping step is determined based on the allocated amount of material flow. As a cross-section, a line orthogonal to the direction of material flow during deep drawing of the sheet metal is defined, and multiple cross-sections are defined, each cut by a plane orthogonal to this line in the view and extending along the thickness direction of the sheet metal before forming.
