Abstract
A silver/silver halide electrode composed of a non-electroconductive support sheet, a silver metal layer and a silver halide layer in order, is improved in its sensitivity by making the silver halide layer almost free from heavy metal element, for instance, by oxidizing the silver metal layer on its surface side with an oxidizing compound containing no heavy metal element or a chelated ferric oxidizing compound in the presence of a halide containing no heavy metal element.
