    • Disclosed is a metal electrode for a living body, which comprises a noble metal wire an an insulating covering layer formed around the periphery of the noble metal wire. At least a part of the portion of the insulating covering layer falling in contact with the noble metal wire is composed of a crosslinked epoxy resin. The outermost layer of the insulating covering layer is composed of a polyurethane. Either or both of a part of the tip end and side face of the metal electrode is directly covered with a polyurethane porous membrane instead of the insulating covering layer. The electrode is advantageous in that (a) the adhesion of a membrane to the insulating covering layer and the adhesion of the insulating covering layer to a metal wire of the electrode are excellent, (b) measurement can be stably performed for a long time, (c) a stablization time required for obtaining a stable current value at the initial stage of the measurement is short, and (d) the electrode can be handled very easily and has enhanced measurement precision and response characteristics.
    • 公开了一种用于生物体的金属电极,其包括贵金属线和形成在贵金属线周围的绝缘覆盖层。 与贵金属线接触的绝缘覆盖层的部分的至少一部分由交联的环氧树脂构成。 绝缘覆盖层的最外层由聚氨酯构成。 代替绝缘覆盖层,直接用聚氨酯多孔膜覆盖金属电极的前端和侧面的一部分中的任一个或两个。 该电极的优点在于:(a)膜与绝缘覆盖层的密合性以及绝缘覆盖层与电极的金属线的密合性优异,(b)长时间稳定地进行测定, (c)在测量初期获得稳定电流值所需的稳定时间短,(d)可以非常容易地处理电极,并具有提高的测量精度和响应特性。
