The present invention relates to a bone grafting substitute and to a method for manufacturing same. The method for manufacturing the bone grafting substitute according to the present invention enables production of a bone grafting substitute which, compared with existing xenograft-derived bone grafting substitutes, has superior biocompatibility due to a lower protein content and which can fuse well in the tissues of a graft site without an inflammatory reaction, and furthermore, the method can provide increased osteoblast adhesion by treating surfaces of the bone grafting substitute with an acidic amino acid, and can provide improved conduction of newly-generated bone by introducing a bioactive factor.
