We studied the temperature dependence of the electric resistivity in single crystal Pr$_{0.7}$(Sr$_{0.28}$Pb$_{0.02}$)MnO$_3$ samples in the temperature interval $20 \div 325$ K. The results demonstrated a maximum of resistivity at $T = 250$ K. This maximum was due to the metal-insulator transition related to the ferromagnetic-paramagnetic phase transition.
