Disclosed is a method for manufacturing a monoclonal antibody without using animal individuals. This method includes a step of introducing a DNA fragment comprising a gene that encodes a secretory signal, a gene that encodes a nanobody, and a gene that encodes a peptide barcode, or a vector containing the DNA fragment, into a yeast cell; and a step of collecting a polypeptide comprising the nanobody and the peptide barcode that has been expressed in the cell and secreted to the outside of the cell. According to the method, it is possible to manufacture a monoclonal nanobody more efficiently in a shorter period of time without using animal individuals.
