Electron cloud causes a fast head-tail instability above a threshold density. Experiments at KEKB showed synchro-betatron sideband, which indicates the head-tail instability. The sideband appears near νy+kνs, where 1<k<2, that differs from ordinary instability seen near νy-νs. We investigate the origin of the sideband using a computer simulation.
