We discuss production of light elements (Li, Be) in energetic type Ic supernovae (SNe Ic) and how newly synthesized light elements are transferred to stars of the next generation. We have pointed out that spallation reactions involving N and He become important in an explosion of a rotating metal-poor star if the progenitor still keeps a fraction of the He layer at SN explosion. In this kind of explosions, 6Li is produced by a fusion reaction He+He. Simultaneously, most of Be is produced through the spallation reaction He+N. This scenario suggests that there must be intrinsic scattering in abundance of Li isotopic ratios among metal-poor stars because the mass range of stars concerned here is limited to ≳ 40 M⊙ and light element yields should be sensitive to the degree of rotation.
