In this article, we review recent NMR studies of Fe-based superconductors. We also report our 75As-NMR and dc resistivity measurement of BaFe2As2 under high pressure P. The T-P phase diagram of BaFe2As2 determined from resistivity anomalies and the 75As-NMR clearly revealed that the antiferromagnetic anomaly is quite robust against P. The NMR measurement under P beyond 3 GPa is needed in order to determine the ground state of BaFe2As2 under P. In addition, we report recent development of NMR technique under high P.
