1. A forming method for pressing a forming die against a stacked body in which a plurality of sheet-shaped composite materials including a fiber base material and a resin material are stacked to form the stacked body into a shape of a forming jig, in which
the forming jig extends in an axial direction, and has, in a width direction that is orthogonal to the axial direction, a bottom region having a first height, a top region having a second height higher than the first height, and a wall region that is adjacent to both the bottom region and the top region and has a height gradually decreasing from the second height to the first height,
the forming die has a shape corresponding to the top region and the wall region of the forming jig, and includes
a main body portion,
a plate-shaped forming portion having a base end portion attached to the main body portion to be swingable around a swing shaft extending in the axial direction, and a contact surface formed in a shape corresponding to the wall region, and
a pressurizing portion that generates a pressurizing force by which a tip end portion of the forming portion presses the stacked body against the wall region, when the forming die is moved to approach the bottom region,
the forming method comprising:
a forming step of moving the forming die or the forming jig such that the forming die approaches the bottom region in a height direction that is orthogonal to both the axial direction and the width direction, and forms the stacked body placed on the top region of the forming jig along a shape of the forming jig, wherein
in the forming step, when the tip end portion reaches a predetermined position in the height direction, the contact surface is brought into contact with a region of the stacked body formed along the wall region by the tip end portion to maintain a state where the stacked body is pressed against the wall region.
