The antibodies according to the invention is an antibody that binds to HBsAg of hepatitis B virus (HBV) neutralizing the hepatitis B virus, that the surface of the antigen binding site of an antibody according to the invention that region to play an important role in virus replication was confirmed in the conventional case where the variation occurs in this portion, because virus replication is remarkably inhibited HBV virus is at least a part has not cause the variation. Therefore, in the present invention, derived from the patient to the antibody according to the invention in a conventional virus replication resistance of YMDD produced by the inhibitor of hepatitis B virus, or derived from blood plasma HBIG (hepatitis B immunoglobulin) G145R mutation in the HBV surface antigens that do not combine bond It was confirmed through the virus, using the chimpanzee is the only animal model of hepatitis B virus was confirmed in vivo efficacy of an antibody according to the invention. As a result, the wild type hepatitis B virus albeit it was confirmed that have a neutralizing potency in the in vivo model. Thus the antibodies of the present invention can be confirmed that all even for variants derived from the G145R hoepihyeong and several patients of YMDD variants with the surface antigen in the polymerase of the wild type hepatitis B virus, as well as the hepatitis B virus have a binding capacity there, as well as the wild type hepatitis B virus can be used effectively to prevent or treat the infection of the mutant viruses.
