摘要： In a method for producing a heat radiating plate 20, the method containing the steps of: finish cold-rolling an annealed material to obtain a strip; causing the strip to wind in the shape of a coil to prepare a coil stock; unwinding the coil stock by means of an uncoiler 10 to obtain a strip 12; causing the strip 12 to pass through a gap between the rolls of a leveler 14 to correct the shape thereof; progressively feeding the corrected strip 12 to a progressive die 18 via a feeder 16 to progressively press-working the strip 12 to produce a heat radiating plate 20, the finish cold-rolling is carried out so that a ratio of the Vickers hardness HV after the finish cold-rolling to the Vickers hardness HV before the finish cold-rolling is not less than 1.2, and the corrected strip 12 is allowed to bend due to its own weight between the leveler 14 and the feeder 16 so that the minimum value of deflection (L1−L0) is 0.5 to 2.0 m assuming that L0 is a distance between a roll at the last sending side of the leveler 14 and a roll at the first entrance side of the feeder 16 and that L1 is the length of the strip 12 between the roll at the last sending side of the leveler 14 and the roll at the first entrance side of the feeder 16.
