摘要:
Provision of a porous ceramic material which rapidly induces bone tissue formation and has practical strength.A porous ceramic material 11 having substantially unidirectionally oriented pores 12, a porosity of 40-90%, and an average open area of one pore of 0.05×10−3-50×10−3 mm2 both in a first sectional surface perpendicular to the pore 12 orientation direction and a second sectional surface parallel to the first sectional surface and 5 mm distant from the first sectional surface in the pore 12 orientation direction. Using the material 11, when a cylindrical test piece (diameter 3 mm×height 5 mm, the pore 12 array direction as a height direction) made of the material is dipped in polyethylene glycol up to 1 mm from one end thereof, polyethylene glycol permeates through the whole test piece preferably within 30 seconds.
