Summary:A powder compacting method for producing a green compact having a constant height by pressure molding material powder while keeping a constant gap between upper and lower punches, comprising a step for filling the cavity with material powder, a step for driving the upper and lower punches to pressure mold the material powder filling the cavity, a primary driving step for driving any one punch until the thickness of the cavity formed between the upper and lower punches exceeds a target molding thickness, and a secondary driving step for measuring the gap between the upper and lower punches and driving any one punch until the gap reaches the target molding thickness.
