PROBLEM TO BE SOLVED: To provide a plate for press-forming which can improve the stability and durability of the sliding movement of a movable part. SOLUTION: The plate for press-forming has a plate main body 2 piled up with many sheet materials 1 and a dislocation prevention part 3 which protrudes from the plate main body 2 laid on the sheet material 1 to overlap each other and is arranged close to the end surface of the sheet material 1. The plate for press-forming which forms the dislocation prevention part 3 expandably/contractably and forms the part 3 contractably by the pressure when the sheet materials 1 are pressed through the plate main body 2 is concerned. A housing space 6 is formed in a fixed part 4 set in the plate main body 2 and opened to the tip surface of the fixed part 4. The movable part 5 is inserted slidably into the housing space 6, and the tip of the movable part 5 is protruded from the tip surface of the fixed part 4, so that the dislocation prevention part 3 in which the movable part 5 is slidable in relation to the fixed part 4 is formed.
