PROBLEM TO BE SOLVED: To provide a die casting method with which satisfactory fluidity is achieved, and further a molten metal is solidified at a suitable speed. SOLUTION: A part of the cavity forming face in a die casting mold 12 is covered with a surface treatment layer 24 whose thermal conductivity increases when the pressure to be acted increases, thus, satisfactory fluidity is maintained at the cavity forming face covered with the surface treatment layer 24 till the molten metal is completely filled into the cavity 9, and it is cooled at the cavity forming face covered with the surface treatment layer 24 whose thermal conductivity is increased after the molten metal is completely filled into the cavity 9.
