An object of the present invention is to provide a peptide capable of inducing a superior or new neutralizing antibody against HIV, so that HIV infectious disease can be prevented and treated or a greater variety of preventive or therapeutic options can be offered. This object is achieved by using a peptide inducing an HIVs three-dimensional structure-recognizing antibody that recognizes a trimer region of C34, wherein three molecules of a derivative of a helical region C34 peptide at C-terminal region of transmembrane protein gp41 of an HIV particle are ligated via a C3-symmetric template compound having three equivalent linker structures.
