It is well known that the superconductive phase is related with the ordering of Cu and Fe, and with the oxygen deficiency in FeSr $_{2}$ YCu $_{2}$ O $_{6+delta}$ . We investigated the oxygen deficiency of FeSr $_{2}$ YCu $_{2}$ O $_{6+delta}$ by neutron diffraction method. It was shown that non superconductor phase was stable around the oxygen content 6+ = 7 and that the superconductive phase was appeared at 7.6 of the oxygen content 6+.
