Abstract
Provided is an economical long-life insoluble anode capable of maintaining an anode function stably for a long time even if it is used in a part where severe consumption occurs to generate a cathodizing phenomenon, and also capable of reducing the amount of an electrocatalyst used as much as possible. To realize this, on the surface of a metal substratecomposed of a titanium plate, a porous layerincluding a sintered body of a spherical titanium powder is formed as a base layer. An electrocatalyst layeris formed from the surface of the porous layerto its inside. A part of the electrocatalyst penetrates into the porous layer, which provides an incomparably stronger anchor effect than the case of a blast treatment. Even when parts exposed from the porous layerare peeled off and dropped off, the anode function is maintained by the electrocatalyst left in the porous layer
