We have done the pressure experiment of a ferromagnet URhGe with the orthorhombic crystal structure by measuring the electrical resistivity. Two ferromagnetic ordering temperatures $T_{rm C2}$ =30 K and $T_{rm C2}$ =25 K indicate a different pressure dependence. $T_{rm C2}$ is approximately unchanged, 30 K at ambient pressure and 40 K at 6-8 GPa, while $T_{rm C1}$ decreases with increasing pressure and most likely becomes zero at 8 GPa. URhGe is found to be ferromagnetic even at 8 GPa, and then the and values of the electrical resistivity are unchanged against pressure.
