Osteoblast activity is promoted and a large amount of extracellular substrates are produced so as to promote cell proliferation and/or differentiation. A material for repairing biological tissues, the material comprising a biocompatible material containing at least one of niobium and tantalum, is provided. These metal salts are not toxic even at high concentrations, and can activate osteoblasts to increase the production quantity of extracellular substrates. The material for repairing biological tissues is manufactured by mixing a metal salt solution, a calcium compound, and a phosphate compound (S4), then coprecipitating the metal-containing calcium phosphate. |
