A press forming die assembly for press forming a blank material includes a draw forming portion that the blank material flows and a draw bead for controlling the amount of the blank material flowing into the draw forming portion. A first draw bead is provided at a periphery of the draw forming portion in a direction substantially parallel to an outer peripheral shape of the draw forming portion. A second draw bead extends from the first draw bead toward the outside of the draw forming portion in a direction intersecting the first draw bead. The blank material includes a thick sheet portion having a greater thickness than the other portion or a high rigidity portion having a higher rigidity than that of the other portion. The second draw bead is provided at a portion corresponding to the thick sheet portion or the high rigidity portion of the blank material.
