PURPOSE:To develop bending strength of 3,000kg/cm<2> or more and fracture toughness of 35MPa.m<1/2> or more, by containing a large amount of an apatite or whitlockite crystal. CONSTITUTION:A glass baked body contains a large amount of apatite or whitlockite excellent in the compatibility with a living body. As a reinforcing material, zirconia, alumina or SiC having heat resistance and high tensile strength is used. This skin piercing terminal is prepared by mixing the above- mentioned glass powder and the reinforcing material in a predetermined ratio and receiving the resulting mixture in a mold to heat-treat the same. The shape of the terminal is not especially limited. A large number of piercing holes 6 piercing from the bottom surface 2 of the terminal to the upper surface 4 thereof are provided. Head wires electrically connecting the body and the outside thereof are inserted in the piercing holes. |
