Abstract
A formed material is manufactured by performing forming including at least one drawing-out process and at least one drawing process performed after the drawing-out process. A punch 31 used in the drawing-out process is formed to be wider on a rear end side than on a tip end side. By pushing a raw material metal plate into a pushing hole 30a together with the punch 31, ironing is performed on a region of the raw material metal plate corresponding to a flange portion.
