PROBLEM TO BE SOLVED: To obtain a molding of a high accuracy by controlling a filling balance in a cavity with a simple constitution. SOLUTION: An injection molding apparatus 1 is switched so that a pressure becomes constant after the speed of a screw is controlled to become constant first when the screw of an injection device is moved to inject while a resin material is injected while the resin material is being melted. The viscosity of the melt of the resin material is obtained from the moving time, etc. of the screw in the state that the pressure is constant, compared with a predetermined allowing range, and whether the present viscosity of the resin material is the viscosity suitable to mold accurately is judged.
