Abstract
By adding the Dirac action on the world sheet, an effective action is obtai ned by integrating over the four-dimensional fermion fields pulled back to the world sheet. This action consists of the Nambu-Goto area term with a ri ght dimensionful constant in front, extrinsic curvature action, and the top ological Euler characteristic term. The divergent coefficients in front of these terms are absorbed in the rigid string action without fermions.
