PROBLEM TO BE SOLVED: To provide a corrosion sensor which is excellent in manufacturability, which has an effectively-protected detector, and which achieves the improvement in accuracy of detecting corrosion.SOLUTION: A corrosion sensor which detects the progress of corrosion of a steel material in a concrete structure includes: a conductor pattern part 101 formed by an iron foil material made by rolling iron; a base plate 102 holding the conductor pattern part 101; and a cover part 103 which is formed by an alkali soluble metal stable in the atmosphere and soluble in concrete, mortar, and paste and which covers the conductor pattern part. Electric characteristics of the conductor pattern part 101 are changed by a corrosion factor of the steel material in the concrete structure. |
