    • 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 substrate 10 composed of a titanium plate, a porous layer 20 including a sintered body of a spherical titanium powder is formed as a base layer. An electrocatalyst layer 30 is formed from the surface of the porous layer 20 to its inside. A part of the electrocatalyst penetrates into the porous layer 20, which provides an incomparably stronger anchor effect than the case of a blast treatment. Even when parts exposed from the porous layer 20 are peeled off and dropped off, the anode function is maintained by the electrocatalyst left in the porous layer 20.
    • 本发明提供一种经济的长寿命不溶性阳极,其能够长时间稳定地保持阳极功能,即使将其用于发生剧烈消耗的部分以产生阴极现象,并且还能够减少用作电催化剂的量 尽可能的 为了实现这一点,在由钛板构成的金属基板10的表面上形成包括球形钛粉末的烧结体的多孔层20作为基底层。 从多孔层20的表面到其内部形成电催化剂层30。 电催化剂的一部分渗透到多孔层20中,与喷砂处理的情况相比,其提供了无与伦比的锚效应。 即使从多孔层20露出的部分被剥离掉,也可以通过留在多孔层20中的电极保持阳极的功能。
