This press forming method includes a first drawing step for forming a first drawn step portion, a second drawing step for forming a second drawn step portion, and a finishing step for completing a stepped portion. In the first drawing step, a first outside curved portion is formed to the outside of a second outside curved portion with respect to an extension region of a character line, and a first parallel portion is formed to the same depth as the drawn depth of a second parallel portion. In the second drawing step, a second inside curved portion having a greater curvature than a first inside curved portion is formed.
