The present invention relates to a membrane having bound thereto an antibacterial peptide that binds to collagen, and more particularly to a collagen membrane comprising a fusion peptide of a collagen-binding peptide and an antibacterial peptide, fixed to the collagen surface.The present invention provides a collagen membrane having surface activity by a fusion peptide bound to the surface thereof. When the collagen membrane is transplanted in vivo, the retention time of the fusion peptide in a local region can increase, and the fusion peptide can promote the cell migration, proliferation and differentiation associated with bone tissue regeneration, thereby maximizing the ability to regenerate bone tissue. Thus, the collagen membrane contributes to the development of therapeutic technology for bone induction and regeneration. Also, the fusion peptide may be applied to other types of graft materials made of collagen. In addition, the collagen-binding peptide of the fusion peptide can also be bound to peptides having the effect of regenerating other tissues, and thus can be applied as a biomaterial for regeneration of other tissues such as the skin.
