115In-NMR measurements of the unconventional superconductor CeCoIn5 reveal an unusual temperature dependence of the Knight shift near the upper limit of Hc2. From a simulation analysis, the present NMR study provides a direct evidence at a microscopic point of view that the Fulde-Ferrell-Larkin-Ovchinikov (FFLO) state is realized at the high field SC phase in CeCoIn5.
