We study the equation of state (EOS) of nuclear matter as well as the properties of unstable nuclei for supernova explosion and r-process in the relativistic many body approach. We provide the EOS table that covers a wide range of density, composition and temperature in supernova explosion by the relativistic mean field (RMF) framework, which is based on the relativistic Br6ckner-Hartree-Fock theory and is checked by the experimental data of unstable nuclei. The relativistic EOS table, thus obtained, is successfully applied to the hydrodynamical simulations of supernova explosion. We perform also the r-process simulations of the neutrino-driven wind from the proto-neutron star and show that the neutrino-driven wind in supernova explosion is a promising site for the r-process to create heavy elements,
