This pressing apparatus shapes a plate material with a die including an upper die and an upper movable die that is provided so as to be able to move toward and away from the upper die. The pressing apparatus includes: a pair of upper fixed plates that are provided at a distance from each other in a pressing direction in which the die presses the plate material and that are driven by a driving mechanism so as to move the upper die up and down with respect to the plate material; and an upper movable plate that is provided between the pair of upper fixed plates so as to be displaceable in the pressing direction with respect to the upper fixed plates and that, when pressed by the upper fixed plates, presses the upper movable die in the pressing direction such that the pressing force of the upper movable die exerted on the plate material can be changed. A plurality of the upper movable plates are provided and stacked in the pressing direction between the pair of upper fixed plates.
