Abstract
A press forming process forms a blank, which is the material to be pressed, into a product having a predetermined shape including a continuous hat-shaped section in the longitudinal direction and a curved portion protruding toward the top surface side in the longitudinal direction. In the press forming process, an intermediate product which has an excess thickness portion formed at a part of the curved portion of the product and protruding higher than the top surface of the product is formed while constraining the portion of the intermediate product other than the excess thickness portion until the excess thickness portion projects in a direction opposite to the protrusion direction thereof, whereby the intermediate product is formed into a predetermined shape.
