Abstract: The existence of the intermediate phase between hadron and quark phases, i.e., the multi-quark bag phase, is considered. The negative surface energy is introduced phenomenologically on the basis of the statistical quark bag model in order to ensure that the smallest bag is most stable. However, with the increase of the quark number density in the bag, the surface energy becomes unimportant in comparison with the kinetic energy of the quark, and it is well known that the mass of the bag is proportional to 3/4 power of the quark number in the naive bag model. Thus the multi-quark bag becomes stable at high quark density. The above property suggests a possibility of the hadron-multiquark bag phase transition.
