We have measured the temperature dependences of Rho and Chi forFe-substituted La_2-x_Sr_x_Cu_1-y_Fe_y_O_4_ in the overdoped regime, in orderto investigate Fe-substitution effects on electronic properties around x=0.22.  From the Rho measurements, it has been found around x=0.22 that the values ofRho are large at room temperature and that Rho exhibits a pronounced upturn atlow temperatures. Moreover, from the Rho and Chi measurements, it has beenfound that T_c_ is anomalously depressed around x=0.22. These results indicatethat the electronic anomalies around x=0.22 are enhanced by Fe substitution,which might be related to the development of stripe correlations by Fesubstitution.
