We calculate the abundances of $^{7}$Li, $^{11}$B, $^{92}$Nb, $^{98}$Tc,$^{138}$La, and $^{180}$Ta produced by neutrino $(\nu)$ induced reactions in acore-collapse supernova explosion. We consider the modification by $\nu$self-interaction ($\nu$-SI) near the neutrinosphere and theMikheyev-Smirnov-Wolfenstein effect in outer layers for time-dependent neutrinoenergy spectra. Abundances of $^{7}$Li and heavy isotopes $^{92}$Nb, $^{98}$Tcand $^{138}$La are reduced by a factor of 1.5-2.0 by the $\nu$-SI. In contrast,$^{11}$B is relatively insensitive to the $\nu$-SI. We find that the abundanceratio of heavy to light nucleus, $^{138}$La/$^{11}$B, is sensitive to theneutrino mass hierarchy, and the normal mass hierarchy is more likely to beconsistent with the solar abundances.
