Abstract
This paper proposes a new possibility of the collective neutrino oscillation in core-collapse supernovae. Neutrinos scattered on nuclei in the pre-shock region induce the fast flavor instability in the outward direction and may have some observational consequences for core-collapse supernovae neutrinos.
