Abstract: A device and a process for producing a corrugated plate having a plurality of bent-into-contact portions extending in parallel on one face of a metal plate employs a number of steps. A first pressing step sequentially molds a plurality of U-shaped bent portions in the metal plate. A second pressing step sequentially molds the bent-into-contact portions by sequentially crushing the plurality of U-shaped bent portions. In the first pressing step, the U-shaped bent portions are fed in a direction orthogonal to the direction of the U-shaped bent portions, and positioned, and are pressed in a state in which the position is released. In the second pressing step, another face of the metal plate is pressed flat while molding the bent-into-contact portions by pressing the U-shaped bent portions from both sides.
