Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a production method for a calcium phosphate-based porous ceramic sintered compact having moderate porosity and high strength. SOLUTION: This method for producing a calcium phosphate-based porous ceramic sintered compact having 5 to 50% of porosity by utilizing the gelation of a water soluble polymer comprises (1) making a slurry containing a calcined calcium phosphate-based ceramic powder and a water soluble polymer compound, (2) pulverizing and dispersing the ceramic powder in the slurry by agitating it, (3) performing a gelation, and (4) sintering after drying.
