In this study, effects of jet-like explosion in collapse-driven supernovae are discussed. In particular, we calculate in detail the explosive nucleosynthesis and growth of Rayleigh-Taylor instabilities in axisymmetrically deformed collapse-driven supernovae. As a result, it is shown that some problems can be solved which can not be explained well by the conventional spherical explosion models. The main effects of the axisymmetric explosion obtained in this study are as follows: (1) 44Ti is synthesized in a sufficient amount to explain the tail of the bolometric light curve of SN 1987A. (2) The large amount of 44Ti in Cassiopeia A, that is suggested by observations, can also be explained. (3) High-velocity element of the heavy nuclei ejected from SN 1987A can be explained well.
