To provide a method and an apparatus for press-forming a metal plate by which cracking is suppressed and the dimensional accuracy is improved without lowering a production rate.

A material 10 is preformed by increasing or decreasing the pressure in a space M and a space N by supplying or discharging gas to or from the space M and the space N which are formed with the material 10, a punch 11, etc. by interlocking with the lowering of a die 13. After that, either or both of the regular forming of the material 10 with a die (punch 11 and die 13) or assistance to the forming by supplying or discharging the gas during forming the material 10 with the die are performed.
