Summary:Provided is a roll-press machine provided with a wrinkle occurrence prevention device for suppressing occurrence of wrinkles caused by a roll-pressing operation on a coated part and an uncoated part of an electrode plate, and a roll-pressing method. A work roll having a diameter smaller than that of the pressing roll is pressed to allow the uncoated part to be rolled between the pressing roll and the work roll, and the work roll is held by two backup rolls arranged in a V-shape formation so that the work roll can press the uncoated part with a pressing force uniform width-wise.
