• To obtain the nuclear data for 237Np which plays an important role in high burn-up reactors and transmutation systems, we measured neutron-induced fission cross section ratios of 237Np relative to 235U between 6 and 120 keV using a pulsed white neutron source produced by the 4.5 MV Dynamitron accelerator of Tohoku University. The fission cross section ratios were measured by two separate runs with the experimental erros of 7% to 25%. The results by two separate runs agreed within the experimental erros. The fission cross section of 237Np was deduced by averaging two results and by using the fission cross section of 235U taken from JENDL3.2. The present results agreed with the result of Hoffman et al. and was consistent with the newest experimental result by Yamanaka et al. The present result around 10 keV agreed with JENDL3.2, while those near 100 keV were close to ENDF/B-VI.
