PURPOSE:To easily produce a thin type sintered metallic body having an intricate shape by using a slurry prepd. by suspending sinterable powder metal into a liquid mixture composed of a synthetic resin emulsion and water and using water-absorptive heat resistant molding tools. CONSTITUTION:The slurry is prepd. by suspending the sinterable powder metal into the soln. mixture composed of the synthetic resin emulsion and water. The slurry S is poured into a cavity 11 which is delineated of the water- absorptive and heat-resistant punch 8 and die 10 to a thin face-to-face space. The slurry S is dehydrated by the water absorption effect of the punch 8 and the die 10, by which the shell-like powder molding 14 is formed. The heat- resistant molding tools 8, 10 are installed in a drying furnace 15 to heat and dry the molding. The tools 8, 10 are then installed in a vacuum sintering furnace 16 where the thermal decomposition of the synthetic resin and the sintering of the powder mixture are executed to produce the sintered metallic powder 6.
