Abstract The luminosity limit is derived for the Super-Eddington accretion by obtaining the self-similar solution. The maximum luminosity is about 4.0 x 10³⁷ erg/s(M/Mסּ) or so (significantly less than the Eddington luminosity) due to photon trapping although the accretion rate is Super-Eddington. The radiation spectrum is found to be universal as Fν ∝ ν^-1.
