[Problem] The purpose of the invention is to provide an oriented collagen/apatite material of controlled orientation and a method for producing oriented collagen/apatite materials of controlled orientation. [Solution] This method for producing oriented collagen/apatite materials is characterized in that by preparing oriented collagen and inoculating osteoblasts or mesenchymal stem cells apatite having an orientation substantially coinciding with the direction of the collagen orientation is formed and fixed on the surface and/or interior of the collagen. A preferred embodiment of this method for producing oriented collagen/apatite materials is characterized in that the osteoblasts are osteoblastoid cells or osteoblasts harvested from a live body.
