Zusammenfassung:	PURPOSE:To obtain a sound formed body having little dispersion of content of oxygen even if sharp temp. difference is developed in preform treated body at the time of raising the temp. with hydraulic press HIP treatment by executing the hot isostatic pressurizing treatment after executing soaking treatment to the preform treated body at the specific temp. for the necessary time. CONSTITUTION:Metal powder is packed in a capsule and the sealed preform treated body 1 is heated for the necessary time, and after soaking, this is charged in a pressure vessel 8 and the hot isostatic pressing treatment is executed to this by using liquid having good fluidity or viscous plastic body as pressure medium 7. In this case, after executing soaking treatment to the preform treated body 1 at
