A method for producing a press-formed product including a top plate section having a stepped section in a longitudinal direction that extends from a widthwise end section of the top plate section and crosses at least widthwise part of the top plate section and a vertical wall section adjacent to the top plate section via a ridge section located in the widthwise end section of the top plate section that is an end section where the stepped section is located, the method comprising: a first pressing step of forming an intermediate formed product from a processed material by using first press tooling (20, 40), the intermediate formed product including the stepped section (4, 14) of the top plate section (2, 12), a temporary vertical wall section adjacent to the top plate section (2, 12) via the ridge section (5, 15) and having at least part of a shape of the vertical wall section, and a temporary flange section adjacent to the temporary vertical wall section via a temporary ridge section located in an end section of the temporary vertical wall section that is an end section opposite to the ridge section (5, 15); and a second pressing step of forming the press-formed product from the intermediate formed product by using second press tooling to perform forming with at least part of the top plate section (2, 12) of the intermediate formed product restricted; characterised in that in the second pressing step the temporary ridge section is moved toward the temporary flange section in a way that the temporary flange section is successively bent and thus formed into the vertical wall section of the press-formed product, and in that a height of the temporary vertical wall section adjacent to the top plate section (2, 12) lower than the stepped section (4, 14) of the intermediate formed product is 50% of a height of the vertical wall section of the press-formed product or less. a first pressing step of forming an intermediate formed product from a processed material by using first press tooling (20, 40), the intermediate formed product including the stepped section (4, 14) of the top plate section (2, 12), a temporary vertical wall section adjacent to the top plate section (2, 12) via the ridge section (5, 15) and having at least part of a shape of the vertical wall section, and a temporary flange section adjacent to the temporary vertical wall section via a temporary ridge section located in an end section of the temporary vertical wall section that is an end section opposite to the ridge section (5, 15); and a second pressing step of forming the press-formed product from the intermediate formed product by using second press tooling to perform forming with at least part of the top plate section (2, 12) of the intermediate formed product restricted; characterised in that in the second pressing step the temporary ridge section is moved toward the temporary flange section in a way that the temporary flange section is successively bent and thus formed into the vertical wall section of the press-formed product, and in that a height of the temporary vertical wall section adjacent to the top plate section (2, 12) lower than the stepped section (4, 14) of the intermediate formed product is 50% of a height of the vertical wall section of the press-formed product or less.
