Submillimetre-wave ESR measurements for Y2Cu2O5; single crystal have been performed for the first time in the frequency region from 60 to 383 GHz using a pulsed magnetic field up to 16 T. AFMR modes below TN = 13 K have been analysed by a model proposed previously, which is essentially the molecular-field theory with the assumption of an S = 1 dimer of two Cu2+ spins. The anisotropies of the system are determined by the analysis, and they are discussed together with the results of our magnetization measurements.
