We measured the temperature dependence of resistivity of (TMTTF)(2)SbF6 under high pressures up to 10GPa. We observed superconductivity in the title compound for the first time when the high pressure exceeded 5GPa. The local maximum of the superconducting transition temperatures was T-c = 2.8 K at 6 and 9 GPa. The superconducting phase of (TMTTF)(2)SbF6 was observed in an anomalously wide pressure range of 5.4 < P <= 9 GPa. We discuss this particular superconducting phase and the electron correlation phase of (TMTTF)(2)SbF6 under high pressure.
