Electrical resistivity measurements have been performed on the heavy fermion superconductor PrOs4Sb12between 0.3 and 300K at pressures up to 9.8GPa. Zero resistivity due to superconducting state was observed at all pressures up to P=9.8GPa. With increasing pressure up to 2.0GPa, superconducting transition temperature Tcwas linearly shifted to lower temperature at a rate of −0.16K/GPa. Effect of pressure on Tcbecame smaller on further pressurization, following that the value of Tcwas saturated to a constant value of 1.3K at high pressure. While, the upper critical field Hc2was strongly suppressed by increasing pressure. Hc2at 9.8GPa estimated from the onset temperature of superconducting transition was 0.91T at 0.5K.
