Abstract
A method for producing a press-formed product includes a first pressing step and a second pressing step. In the first pressing step, an intermediate formed product is formed from a processed material by using first press tooling. The intermediate formed product includes a stepped section of a top plate section, a temporary vertical wall section adjacent to the top plate section via a ridge section and having at least part of the shape of the vertical wall section, and a temporary flange section adjacent to the temporary vertical wall section via a temporary ridge section. In the second pressing step, the press-formed product is formed from the intermediate formed product. In the second pressing step, forming is performed such that the temporary ridge section is moved toward the temporary flange section with at least part of the top plate section of the intermediate formed product restricted.
