We investigated the pressure dependence of the antiferromagnetic transition temperature TN of UPb3 by the electrical resistivity measurement. We found that at low pressures TN increases with increasing pressure. It has a maximum value 38 K at 5 GPa, then decreases with increasing pressure. In addition we observed another resistive anomaly followed by a steep decrease in resistivity below TN under pressure. The maximum pressure of 8 GPa in the present study was not enough to suppress the antiferromagnetic ordering. The critical pressure is estimated to be around 10 GPa.
