High field ESR measurements of the S = 1/2 two-dimensional spin gap system SrCu2(BO3)2 have been performed in the frequency region from 526 to 1620 GHz using pulsed high magnetic fields up to 55 T. Besides the ESR signal which is observed near the EPR line, a number of new ESR signals are observed in the magnetic phase, where the plateau at 1/3 of the saturated magnetization appears on the magnetization curve.
