The oxygen evolution anode for seawater electrolysis was improved for the achievement of the energy system, that is, "Global CO_2 Recycling". The anodes were composed of the electrocatalyst oxide, the intermediate layer and the titanium substrate. Mn_<1-x>Mo_xSn_yO_<2+x> electrocatalyst oxide / Sn_<1-x>Ir_xO_2 intermediate layer/Ti anodes, whose the intermediate layer was prepared from 0.04 M Ir-0.06 M Sn solution, showed the oxygen evolution efficiency higher than 99.8% for more than 4300 h in electrolysis of 0.5 M NaCl solution of pH 1 at the current density of 1000 Am^<-2>.
