Abstract: The present invention relates to an epitope specific to hepatitis B virus surface antigen and a binding molecule binding to the same for neutralizing hepatitis B virus. Since the epitope provided by the present invention is produced by forming a three-dimensional structure and does not comprise a determinant, by which escape mutation is induced against an administration of existing vaccines or HBIg, a composition comprising an antibody biding to the epitope or a vaccine composition comprising the epitope has a very low possibility of causing a decrease in efficacy due to escape mutation. Therefore, such an antibody or vaccine composition can be very effectively used in prevention and/or treatment of HBV.
