PURPOSE: To produce an aromatic sintered body which retains a flavor for a long period of time by sintering a continuous green compact of metal or alloy powder and compressing only the surface or the front layer part with rolls then impregnating an aromatic liquid into the gaps under vacuum.
CONSTITUTION: A powder mixture 1 consisting essentially of powders of metals or an alloy is passed and compressed through and with at least a pair of powder rolls 3 from a hopper 2, whereby the powder is molded to a continuous belt-like green compact 4. The green compact 4 is passed through a sintering furnace 5 and the sintered body 6 is compressed with at least a pair of compression rolls 7 to the extent that only the surface or front layer part is compressed. The sintered body 6 is blanked to a desired shape and, if necessary, the side faces are compressed; thereafter, an aromatic liquid is impregnated under vacuum into the body 6.
