Claim 2:
3. A corrosion rate estimation method performed by a corrosion rate estimation apparatus, the corrosion rate estimation method comprising:
repeating water supply cycles in which water is supplied to soil in which metal to be evaluated is buried and measuring a corrosion rate of the metal in each water supply cycle a plurality of times;
finding a prediction model by accepting as inputs to a machine learning algorithm, cycle numbers of the water supply cycles and corrosion rates, the prediction model representing a future corrosion rate; and
assigning a cycle number and a time point in a cycle at which a desired corrosion rate is to be estimated to the prediction model, and estimating the desired corrosion rate of the metal at the time point.
