It is proposed that the observed X-rays from active galactic nuclei are made up of at least two components: (1) a steeper and softer component, and (2) a flatter and harder component, and that the hard component is due to the Comptonization of the higher harmonics of the cyclotron photons. The hard component is analyzed on the basis of a model which assumes that there exists a supermassive black hole of 10 to the 8th solar masses in the center of an active galactic nucleus, and that sufficient accreting mass is supplied at a rate of 10 to the 26th g/s. The hard component extends to about 3 kT (several hundred keV). Therefore, the detection of a break in the spectra somewhere between 100 and 1000 keV in sources such as NGC 4151 will greatly support the model, though the absence of such a break does not necessarily disprove the model.
