A corrosion prediction device that predicts corrosion indicating the degree to which a metal will corrode in an environment, the device including a storage unit which stores a soil sample that simulates the environment and an electrode unit and has a function of repeatedly performing water supply and drainage with respect to the soil sample; the electrode unit including at least one type of metal pieces; a measurement unit that measures, based on change in water content in the environment in one cycle, a corrosion rate of the metal pieces or a value proportional to the corrosion rate of the metal pieces during the change; a calculation unit that integrates the corrosion rate or a value proportional to the corrosion rate over time and calculates an amount of corrosion or a value proportional to the amount of corrosion; and a prediction unit that determines a constant value of K of the power law and a constant value of n of the power law using a difference between the amounts of corrosion or the values proportional to the amounts of corrosion in different periods.
