CORROSION SENSOR AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a corrosion sensor allowing a sensor region to be inserted into a thin space such as a gap and allowing the corrosive environment property to be finely measured.SOLUTION: The corrosion sensor includes: a common positive electrode 9 in which a plurality of electrode sections 4 are arranged planarly along a surface of a substrate 3; a plurality of insulation units 10 formed on a surface of the positive electrode 9; and a plurality of negative electrodes 11 formed by thinly applying a conductive material having a potential valuable to the positive electrode 9 to respective surfaces of the plurality of insulation units 10. The plurality of negative electrodes 11 are electrically separated from each other so that the plurality of negative electrodes 11 form independent corrosion circuits with the positive electrode 9.
