Abstract
The object of the present invention is to provide a calcium phosphate-collagen fiber composite which has an excellent mechanical property, can induce bone replacement by rapid bone remodeling, and can be used in a high-load region. The object can be solved by a porous composite comprising a calcium phosphate crystal and a collagen fiber at a weight ratio of 80:20 to 20:80, wherein (1) a bioabsorbability of the porous composite is graded, and (2) the density of the porous composite determined by gravimetric method is 300 to 1500 mg/cm3.
