We investigate the r-process that occurs due to the explosion from an inner region of the Fe-core. It is shown that the solar r-process abundances are rather well reproduced for a model of 13 M⊙. We also examine whether the fission affects final r-process abundances by using the full nuclear reaction network with both spontaneous and the β-delayed fission included. Moreover, we pay attention how the mass formula affects the r-process peaks by using two networks.
