Next, the gaseous hydrogen is removed under the reduced pressure, thereafter, carburizing gas is introduced therein, and carburizing is executed preferably under the reduce pressure. The carburizing temp. is controlled to 600 to 1,100 deg.C, desirably to 800 to 1,000 deg.C. As the carburizing gas, a gaseous mixture of hydrocarbon and hydrogen is used.  When the carburizing stage is finished, the gas in the storing chamber is removed under the reduced pressure, inert gas is introduced therein, and sintering is executed under the reduced pressure. The production of the sintered body is executed preferably at an approximately fixed temp of 1,000 to 1,400 deg.C.
