Abstract

To provide a ceramic particle separable composite material having a calcium phosphate sintered body particle with which bioaffinity reduction and solubility change are suppressed as much as possible and which has a smaller particle diameter. A ceramic particle separable composite material comprising a ceramic particle and a substrate, wherein: the ceramic particle and the substrate are chemically bonded to each other, or the ceramic particle physically adheres to or is embedded in the substrate; the ceramic particle has a particle diameter within a range of 10 nm to 700 nm; the ceramic particle is a calcium phosphate sintered body particle; and the ceramic particle contains no calcium carbonate.
