It is to provide an immunocompetent cell that expresses regulatory factors of i mmunocompetent cell immune function and posses ses all of proliferative potential, viability, and the ability to accumulate a T cell, and an ex pression vector of regulatory factors of immune function for generating the immunocompetent cell. An immunocompetent cell expressing a cell surface molecule specifically recognizing a cancer antigen, interleukin 7 (IL-7), and CCL19 is generated. Preferably, the cell surface molecule specifically recognizing a cancer antigen is T cell rece ptor specifically re cognizing the cancer antigen, and the immunocompetent cell is a T cell.
