    • An insoluble electrode that even when used in regions of intense consumption such as one where the phenomenon of conversion to negative electrode occurs, can stably maintain positive electrode functions for a prolonged period of time, and that can minimize the amount of electrode active material used, ensuring long operating life and economic advantage. For realizing this, porous layer (20) of spherical titanium powder sintered is provided as a foundation layer on a surface of metal base material (10) of titanium plate. Electrode active material layer (30) is formed across the surface through interior of the porous layer (20). Portion of the electrode active material penetrates the porous layer (20), resulting in realization of a strong anchor effect not comparable to that exhibited at blast processing. Even if portions exposed from the porous layer (20) are detached or caused to fall, the positive electrode functions can be maintained by the electrode active material remaining in the porous layer (20).
    • 即使用于发生负极转换现象的区域,即使在电力消耗区域中使用的不溶性电极也能够长时间稳定地保持正极功能,并且能够使所使用的电极活性物质的量最小化, 确保长寿命和经济优势。 为了实现这一点,在钛板的金属基材(10)的表面上提供了烧结的球形钛粉末的多孔层(20)作为基础层。 通过多孔层(20)的内部跨越表面形成电极活性物质层(30)。 电极活性物质的一部分穿透多孔层(20),导致实现与喷砂加工时不相似的锚固效果。 即使从多孔层(20)露出的部分脱落或引起下落,也可以通过残留在多孔层(20)中的电极活性物质维持正极功能。
