<p>A layer (2) of a resin having an imide group in its main chain is deposited on the surface of a conductive substrate (1) made of carbon, gold, or the like. The resulting electrode has anion selectivity, does not cause ion to dissolve into a measuring solution and can measure stably an intended anion. When an anion concentration is constant, the electrode can be used as a reference electrode which is hardly affected by ion or dissolved gas, and the like. When a redox function layer is disposed between the conductive substrate (1) and the resin layer (2), the electrode is hardly affected by dissolved gases such as dissolved oxygen.</p> |
