In an insoluble anode for use in an electrolysis step accompanied by oxygen generation, by making the anode exert sufficient durability even in electrolysis accompanied by cathodic polarization besides anodic polarization, a service life of an electrode is prolonged and works of electrode repair, replacement, and the like are reduced. In order to realize this, an active material supporting member made of a porous metal sheet such as an expanded metal, a punching metal, or a bamboo blind-like or net-shaped metal is bonded to a conductive metal as an electrode structure, to configure an electrode substrate. The electrode substrate is coated, on the side to which the supporting member is bonded, with an electrode active material consisting mainly of iridium oxide. Thus, the anode for oxygen generation, which is highly resistant to a cathodization phenomenon, is obtained. |
