Abstract	To search new physics beyond the standard model, upgrade project of KEKB-factory is on the move. In order to gain luminosity, IP beam size become nanometer order. Increment of backgrounds is expected due to gain in beam current and beam density. For the purpose of IR designing, Touschek effect and gas scattering background were simulated for current KEKB and SuperKEKB. The result of current KEKB simulation was compared with experimental data. We confirmed the validity of our simulation framework and obtained detailed under- standing of the background mechanism.
