We construct the holographic model of S\pm multiband superconductor. This system is a candidate to explain the anomalous features of the iron-based superconductors (e.g. LaFeAsO, BFe2As2, and other pnictides and arsenides). We study the framework which allows the formation of the sign-interchanging order parameter. We also calculate the electric AC conductivity, which exhibits a mid-infrared peak, related to the interband interaction.
