REFERENCE ELECTRODE COATED WITH IONIC LIQUID, AND ELECTROCHEMICAL MEASUREMENT SYSTEM USING THE REFERENCE ELECTRODE

摘要

This invention provides a reference electrode (3) that can be downsized and stable in voltage. The reference electrode (3) in accordance with this invention is a reference electrode (3) that does not require an internal aqueous solution such as a KCl aqueous solution and comprises a metal body (31), a slightly soluble salt film (32) that comprises a slightly soluble salt of the metal body (31) and that coats the metal body (31) and a hydrophobic ionic liquid (33) that is arranged to make contact with both the slightly soluble salt film (32) and a sample to be measured.
