Resistivity and static magnetization measurements were performed in the organic compound (TMTTF)2Br. The resistivity was measured with applying pressure up to 2.1 GPa. At ambient pressure the resistance shows a kink at 18 K and the spin susceptibility starts to decrease at 19 K. The resistance shows no characteristic structure around TAF. With increasing pressure, the kink structure changes its shape to a peak in the derivative of the logarithm of the resistance with 1/T. The peak temperature increases with increasing pressure up to 0.3 GPa and is 4-8 K higher than TAF. This indicates the existence of another phase just above the AF state.
