PROBLEM TO BE SOLVED: To provide a hydraulic forming method for a metal plate by which the metal plate can be formed even into a shape hard to form. SOLUTION: The hydraulic forming method for the metal plate 1 is divided into several forming processes. The face of the metal plate, to which the liquid pressure is applied, is changed in a certain time and in its succeeding time (for example, the first time in the figures (a) to (d) and the second time in the figures (e) to (g)), namely, the pressure applied face is reversed from the front surface to the rear surface.
