After gelling the apatite / collagen composite fiber and the dispersion containing collagen and water, the obtained gel body is made into a porous body by freezing and drying, and a porous body including the apatite / collagen composite fiber is produced by crosslinking the collagen in the porous body. In the process, the average pore diameter of the porous body is controlled by the solidification time of the gel body in the freezing step. |
