Abstract
A sheet-type, highly polymerized composite electrode used for measuring ionic concentration includes a thin film ion-selective responsive membrane formed on an upper surface of an insulating support layer by sequentially dripping an ion-selective responsive membrane paste containing solvent onto the support layer. The ion-selective responsive paste has a polymerization degree sufficient to provide an enduring ion-responsive membrane without any reinforcing structure.
