PROBLEM TO BE SOLVED: To provide an injection molding method for molding moldings having uniform and high quality by stabilizing control of pressure in processes from an injection process to a pressure holding process and preventing the occurrence of overshooting of pressure. SOLUTION: In this injection molding method for switching the control in the processes from the injection process to the pressure holding process from speed control to pressure control, a target speed value for speed control is convergently changed to perform premolding for several times, the highest injection process speed V is obtained as the first injection speed V1 without causing overshooting of pressure, and the injection process speed V in the speed control is changed from the initial set injection speed V0 specified per product to the first injection speed V1 for injection molding.
