PROBLEM TO BE SOLVED: To provide a bone regeneration material which has excellent shapability, elastic modulus and high bone regeneration ability and can form the same shape as that of a bone before breakage by sufficiently being replaced with a newly generated bone.SOLUTION: The bone regeneration material includes a complex between octacalcium phosphate fine powder and gelatin. A method for generating the bone regeneration material includes a step of freeze-drying a dispersion liquid prepared by dispersing the octacalcium phosphate fine powder in a gelatine solution.
