The pressure dependence of transport properties in CeRhIn5, was studied up to 8.5 GPa by using a diamond-anvil cell. The electrical resistivity does not follow the T2-dependecne of a Fermi liquid nature under any pressure. In this non-Fermi liquid state, superconductivity was observed in a wide pressure range of 1.5 GPa < P < 7.6 GPa. The superconducting temperature TC has a double-maximum structure with a minimum at 5.2 GPa. A maximum of TC = 2.2 K was observed at P = 2.5 GPa, where the corresponding electrical resistivity just above TC has the maximum. The upper critical field HC2 and the magnetoresistances were also investigated under pressure.
