An HLA-binding peptide binding to an HLA-A type molecule, said HLA-binding peptide comprising at least one type of amino acid sequence selected from the group consisting of SEQ ID NOS: 1 to 60, and not less than 8 and not more than 11 amino acid residues is provided. Any of the amino acid sequence is predicted to have the binding property to a human HLA-A24 molecule or a human HLA-A2 molecule by a predicting program using an active learning experiment method as illustrated in FIG. 1.
