Abstract

Through the present invention, a differential-thickness blank as an integrated object having a plate thickness distribution is provided by a simple method. A first blank (2) as a blank having larger dimensions than the dimensions of a desired blank (1) for use in press molding is drawn using a punch (3) and a die, and the drawn first blank (2) is trimmed to the necessary dimensions and used as the abovementioned desired blank (1) for use in press molding. During drawing, the punch (3) has a punch bottom having larger dimensions than the dimensions of the desired blank (1), and restriction of a portion of positions on the external periphery of the first blank (2) during drawing is made relatively stronger, whereby a portion of the plate thickness in the desired blank (1) after drawing is relatively reduced to obtain a blank having a plate thickness distribution.
