The influence of hydrostatic pressure on electrical resistance of a perovskite manganese oxide (La_0.1, Ce_0.4 Sr _0.5)MnO₃ has been investigated under pressures up to 1.8 GPa in the temperature range of 77-320 K. With application of pressure, Curie temperature (T_c) increases at a rate of dT_c/dp = + 1.9 K/GPa. It is also found that the coefficient of -log T term originated from Kondo-like effect decreases with increasing pressure and the resistance maximum temperature (T_max) shifts largely to lower temperature at a rate of dT_max/dp = -86K/GPa.
