ABSTRACT:
A ceramic member for a living body includes a first end portion formed of a material having affinity with a living body and consisting of a dense material, and a second end portion formed of a material having affinity with a living body and consisting of a porous material. A method of manufacturing a ceramic member for a living body, includes the steps of mixing a ceramic powder having affinity with a living body, water, and a binder to prepare a dense material slurry, mixing a ceramic powder having affinity with a living body, water, a binder, and a foaming agent to prepare a porous material slurry, injecting, in order to form a two-layered base material consisting of the dense material slurry and the porous material slurry, the dense material slurry and the porous material slurry obtained in the two steps in a mold such that the dense and porous material slurries are not mixed with each other, and drying the base material, and after the drying step, heating the base material at a predetermined rate, and sintering the base material at a predetermined temperature.
