A press-formed product is manufactured by press-forming a blank material into an intermediate shape, and further press-forming the blank material from the intermediate shape into the press-formed product having a target shape. A product portion of the target shape includes a first ridge line portion and a second ridge line portion each having a radius of curvature of 20 mm or smaller and a bending angle of 130 degrees or larger. The product portion of the intermediate shape has a curved shape having a radius of curvature of 100 mm or larger or a linear shape in a specific cross section. A height of an excess thickness portion of the intermediate shape is higher than 10 mm with respect to a peripheral portion and lower than a height of the excess thickness portion of the target shape.
