PROBLEM TO BE SOLVED: To provide an apparatus and a method for hydraulically forming laminated metal plates with which liquid leakage during the forming is surely prevented, a material is smoothly moved during the forming, a die is not increased in the scale, the yield of the material is improved and which is advantageous cost-wise. SOLUTION: This apparatus has dies 10, 11 for laminating, holding and clamping at least two metal plates 1, 2 and a pouring means 12 for pouring a forming medium W between the metal plates 1, 2 from a hydraulic pressure pouring part 3 and this method is hydraulic forming by which the metal plates 1, 2 are formed into a shape matching to the forming shape part 13 of the dies 10, 11 by the forming medium W. Flexible parts 30, 30A are provided on the metal plates 1, 2 between the hydraulic pressure pouring part 3 and the forming shape part 13 and the material is supplied by moving the metal plates in the flexible parts 30, 30A with the flow-in of the material in the inside of the forming shape part of the metal plates 1, 2 supported with the dies 10, 11 when pouring the forming medium W.
