A calcium phosphate porous sintered body which comprises spherical pores communicating with one another substantially throughout the body with a porosity of 55% to 90%, and has an average diameter of the inter-pore communicating parts of 50 <I>ž</I> m or more, a pore diameter of 150 <I>ž</I> m or more, and a three-point bending strength of 5 MPa or more. A method for producing the porous sintered calcium phosphate comprises preparing a slurry by dispersing or dissolving phosphate powder and an organic material hardenable by cross-linking polymerisation in a solvent, adding a foaming agent, foaming by stirring and/or gas introduction, adding a cross-linking agent and/or cross-linking initiator, moulding the mixture in a die as it hardens, drying and sintering the resulting compact. |
