A pressed component is formed by pressing a preform having a tapered tubular portion and a sloping portion provided at an end of the tubular portion and curved in a circular arc. Pressing is performed by a forming die apparatus including a holding body, a piercing punch, and a piercing die. When the tubular portion of the preform is held by an outer fixing and supporting portion of the holding body and an inner fixing and supporting portion of the piercing die, the forming die apparatus cuts off a portion of the sloping portion using an outer cutting edge of the piercing punch and an inner cutting edge of the piercing die and then causes a pressing portion of the piercing punch to bend and press the remaining portion of the sloping portion within a forming space to form a corner portion.
