We discuss the possibility of the r-process nucleosynthesis in the core-collapse supernova of a low mass progenitor (9Msolar). This progenitor is composed of an O+Ne+Mg core and has a possibility to explode promptly prior to the neutrino heating. We simulate the prompt supernova explosion with one dimensional spherically symmetric hydrodynamics. In our results, this model cannot produce a successful supernova explosion by the prompt shock. We then obtain explosions by artificial enhancement of shock energy, and argue whether this type of supernovae can be the major r-process site in the Galaxy.
