Hadronic matter undergoes a deconfinement transition to quark matter at high temperature and/or high density. It would be realized in collapsing cores of massive stars. The fates of core collapses are investigated for various cases. Equations of state including the hadron-quark phase transition with different values of bag constant are used. As a result, for the case with a small bag constant (i.e. the transition occurs at low density), the second bounce revives the shock wave leading to explosion for the model with 15 solar mass. The systematics on the bag constant is also studied for the black hole formation of a 40 solar mass progenitor.
