The origin of the broad-band photon spectrum of the Crab Nebula is discussed. The synchrotron radiation calculated for the spatial distribution of the nebular magnetic field derived from the MHD flow model is in a good agreement with the observed photon spectrum from radio wavelengths to gamma-rays, up to E_gamma <=1 GeV. The inverse Compton scattering of the accelerated electrons on the synchrotron, ``dust" IR, and 2.7 K microwave background radiation fields is the most effective gamma-ray production mechanism at photon energies above 100 GeV. We argue that the bremsstrahlung radiation of relativistic electrons produced in the Crab filaments could play a principal role in the formation of the spectrum of the Crab Nebula in the intermediate energy domain between 1 and 100 GeV.
