[Problem] To obtain a very high frequency of T cells having the same TCR gene reconstitution pattern as the original human T cells in CD8 single-positive cells or CD4 single-positive cells obtained by redifferentiation from human T cells having antigen specificity via iPS cells. [Solution] A method for producing human CD8 single-positive cells or CD4 single-positive cells having antigen specificity, wherein the method comprises a step for differentiating to CD4/CD8 double-negative cells iPS cells induced from human T cells, a step for stimulating the T cell receptor of the CD4/CD8 double-negative cells, and a step for differentiating to CD8 single-positive or CD4 single-positive cells the CD4/CD8 double-negative cells whose T-cell receptor has been stimulated.
