ELECTRODE SUBSTRATE

WIPO Patent Application WO/2023/100694

A1

An electrode substrate comprises an insulation substrate (110) and a reference electrode (120). The reference electrode (120) is formed on the insulation substrate (110). The reference electrode (120) includes a silver layer (121), a first silver chloride layer (122), and a second silver chloride layer (123). The silver layer (121) is formed on the insulation substrate (110). The first silver chloride layer (122) is formed on the silver layer (121) so as to span the area above the insulation substrate (110), and covers the silver layer (121). The second silver chloride layer (123) is formed on the first silver chloride layer (122) so as to span the area above the insulation substrate (110), and covers the first silver chloride layer (122). In an arbitrary vertical cross section, the surface area gap ratio of the first silver chloride layer (122) is larger than the surface area gap ratio of the second silver chloride layer (123).
