To obtain a permanent magnet compact without applying strain to permanent magnet powder, and capable of venting air smoothly, preventing the cracking and deformation of the compact and being filled with high density by charging permanent magnet powder to a previously compacted vessel, orientating it by pulse magnetization or the like, thereafter setting this vessel to a centrifugal separator and executing compacting by centrifugal force.

A vessel previously molded into a conical shape made of a rubber martial of urethane or a heat shrinkable tube of vinyl acetate on the market is charged with a permanent magnet body, which is applied with pulse magnetization and is previously orientated, and temporary compacting is executed. Next, this vessel is set to a centrifugal separator and is compacted. At this time, since the permanent magnet body in the vessel is pressed from the edge part in the circumferential direction by centrifugal force, air venting is naturally executed and strain is not applied to the permanent magnet compact, so that the good permanent magnet compact without causing any cracking and chipping can be obtd.
