We examine the anisotropy of optical conductivity above the Néel temperature in iron arsenides by mean-field calculation in a five-band Hubbard model. In order to represent the anisotropy, we artificially introduce the energy splitting between dzx and dyz. The calculated spectra are not enough to explain the anisotropy observed in experiments. The optical conductivity in the low-energy region is consistent with the observation, while in the high-energy region not. This implies that there should be some other effects to give rise to the anisotropy in the high-energy region.
