Stars with mass more than about 10 M⊙ are known to culminate their evolution as supernova explosion and a huge number of neutrinos should be emitted from the collapsing core. Previous studies for Type II supernovae have revealed that a fraction of the neutrinos can interact with stellar material and induce some characteristic nucleosynthesis of light elements ( 7Li, 11B, 19F) and heavy elements ( 138La, 180Ta). We studied the neutrino-processed nucleosynthesis in Type Ib(c) supernovae whose progenitors have lost their H-rich (and He) envelopes before explosions. We found that Type Ib/c supernovae can produce 11B as much as Type II supernovae.
