Original Abstract Submitted

An electrode of an embodiment includes a porous titanium support and a catalyst layer for electrolysis provided on the porous titanium support and stacked sheet layers and gap layers alternately. A first covering layer including titanium oxide is provided on the porous titanium support on the catalyst layer side. A second covering layer including titanium oxide is provided on the porous titanium support on an opposite side of the catalyst layer. An average thickness of the first covering layer is denoted as D1. An average thickness of the second covering layer is denoted as D2. D1 and D2 satisfies 1 [nm]≤D2−D1≤20 [nm].
