The effect of the shock propagation on neutrino oscillation in supernova is studied paying attention to evolution of average energy of νe and νˉe. We show that the effect appears as a decrease in average νe (in case of inverted mass hierarchy, νˉe) energy at stellar surface as the shock propagates. It is found that the effect is significant 2 seconds after bounce if 3×10−5<sin2θ13<10−2.
