ABSTRACT:
A living body-supporting member having a surface layer with multiple pores regularly arranged therein, in which the porous portions constituting the living body-supporting member are made of ceramics giving no harm to a human body. And a method to perforate multiple pores in a green sheet made of the ceramics, to laminate the green sheets so that pores communicate with each other, and to fire it. The living body-supporting member is coupled with the bone, and there is no risk that it may drop from the supporting portion. Even if the substrate is composed of ceramics, the substrate and the surface layer can be integrally coupled with each other, thereby there is no risk that both of them are separated. Furthermore, according to the above method, the pore shapes of the porous body can be preliminarily designed so that pores communicate with each other while being displaced for every certain depth, and it can be accurately controlled in the production thereof.
