Using a phenomenological two-fluid model we derive the Kerr rotation of the polarization direction of reflected light from the surface of a superconductor in a state breaking time-reversal symmetry. We argue that this effect found recently in the superconducting state of Sr2RuO4 by Xia et al. [Phys. Rev. Lett. 97, 167002 (2006)] originates from the spontaneous magnetization in this superconductor. The temperature and the frequency dependencies of the effect are established. It is shown that the effect is determined by one of two mechanisms depending on the frequency of light that is larger or smaller than the plasma frequency.
