Abstract: PROBLEM TO BE SOLVED: To efficiently produce a ceramic formed compact having a complicated shape. SOLUTION: A ceramic raw material powder is prepared (in step al) and the resultant raw material powder is filled in a metallic mold and press formed (in step a2). The formed green compact is then sintered under atmospheric pressure to prepare plural sintered compacts (in step a3) and each sintered compact is machined to form an intermediate compact of a simple form (in step a4). The formed plural intermediate compacts are arranged at prescribed positions (in step a5). The hot compression superplastic working of at least the one intermediate compact is then carried out to bring the intermediate compacts into contact therewith by the plastic flow. The plural intermediate compacts are then integrally diffused and joined to form the whole shape into a prescribed one (in step a6).  Since the intermediate compacts in the simple form can thereby be combined and joined, the ceramic compacts having the complicated shape can efficiently be produced.
