Artificial living body composite material comprising:
- (a) an artificial bone portion having a predetermined shape and size and consisting essentially of a sintered ceramic material selected from the group consisting of alumina, zirconia and calcium phosphate, said bone potion having a number of spherical independent pores having a size of 1 to 600 .mu.m and communicated with one another and with an exterior space through a number of capillary void paths having a void diameter of 1 to 30 .mu.m;
- and
- (b) an inclusion membrane which covers said artificial bone portion, said inclusion membrane being in the form of a member selected from the group consisting of sheets, tubes and bags, and at least the main component of said membrane being at least one member selected from the group consisting of woven fabrics, knitted fabrics, felts, nets and non-woven fabrics comprising a synthetic polymeric material selected from the group consisting of polyester resins and fluorine-containing organic polymer resins.
