Abstract: PURPOSE: To obtain a suitable reference electrode for electrolyte, insulator and semiconductor system by laminating a polyglutamate layer directly on a substrate made of insulator or semiconductor or on a formed phthalocyaninate and polysiloxane polymer layer. CONSTITUTION: In the reference electrode, a polyglutamate coating is formed on an insulator or semiconductor substrate or on a phthalocyaninate and polysiloxane polymer layer formed on the substrate by a Langmuir's or Blodgett's technique. As the polyglutamate, the copolymer of γ-methyl-L- glutamate and γ-n-alkyl-L-glutamate is used when poly-γ-methyl-L-glutamate and Langmuir' or Blodgett's technique are used. The thickness of the polyglutamate is 3.6 to 180nm and laminated on the substrate. As the substrate, SiO2 /Si substrate is preferably used.
