The first submillimeter wave ESR on triangular lattice antiferromagnet, CuFeO2 has been performed in frequencies up to 762 GHz. The changes of AFMR modes were observed for H∥c, corresponding to the metamagnetic transition which occurred below TN2. In a phase between TN1 and TN2, we observed an easy-plane type AFMR mode which could not explain a partially disordered model suggested by neutron diffraction experiments.
