PROBLEM TO BE SOLVED: To enable to fit well to shape of a bone deficient part, to have biocompatibility and to excellently form bones in the peripheral part of material. SOLUTION: A composite calcium phosphate artificial bone has a block-like calcium phosphate artificial bone at its center, and paste-like calcium phosphate arranged in the pheriphery. The paste-like calcium phosphate comprises calcium phosphate as a main component of power and water as a main component of liquid. The calcium phosphate is one selected from each simple substance of α-tricalcium phosphate or tetracalcium phosphate and mixture thereof, a mixture of α-tricalcium phosphate, tetracalcium phosphate and calcium hydrogenphosphate and/or dicalcium hydrogenphosphate, a mixture of α- tricalcium phosphate and calcium hydrogenphosphate and/or dicalcium hydrogenphosphate, or a mixture of tetracalcium phosphate and calcium hydrogenphosphate and/or dicalcium hydrogenphosphate. |
