Claim 2:
3. A corrosion predicting method executed by a corrosion prediction device that predicts corrosion indicating the degree to which a metal will corrode in an environment, the method comprising:
a measurement step in which, based on change in water content in one cycle in an environment in which at least one type of metal is disposed, a corrosion rate of the metal or a value proportional to the corrosion rate of the metal during the change is measured;
a calculation step in which the corrosion rate or a value proportional to the corrosion rate measured in the measurement step is integrated over time, and an amount of corrosion or a value proportional to the amount of corrosion is calculated; and
a prediction step in which, based on the amount of corrosion or the value proportional to the amount of corrosion and rainfall information for a predetermined period, a constant value of K of a power law is determined, and a constant value of n of the power law is determined using a difference between the amounts of corrosion or the values proportional to the amounts of corrosion in different periods.
