A biomedical material for use as artificial bone and dental root is provided which takes the form of a sintered composite body comprising a crystalline calcium phosphate matrix and inorganic whiskers dispersed therein. The inorganic whiskers contain at least one oxide selected from the group consisting of silicon oxide, aluminum oxide, calcium oxide and magnesium oxide. The matrix of tricalcium phosphate or apatite preferably has a grain size of 0.05 to 30 mm
