<p>The sheet-type electrode for ion measurement comprises a thin-film ion selective responsive membrane (20) formed on an upper surface of an insulating support layer (10) by sequentially dropping of an ion selective responsive membrane paste containing a solvent, to which said insulating support layer is soluble, polyvinyl chloride resin powders and an ion response substance. For avoiding a swelling of the membrane, in particular during the measurement of liquids, and for improving the abrasion resistance according to the invention, highly polymerized polyvinyl chloride resin powders are used having a polymerization degree of 3,800 to 20,000. <IMAGE></p> |
