| 1. A method for manufacturing a sintered compact, comprising:
molding a green compact by compacting hydroxyapatite powder with applying a pressure of 1 ton/cm2 or higher thereto; and
sintering the green compact in an oxygen-containing atmosphere, in which the partial pressure of oxygen in the oxygen-containing
atmosphere is 380 mmHg or higher, at a temperature in the range of 925 to 1,300° C. to obtain a sintered compact.
