A first estimation function unit estimates, on the basis of a particle diameter of soil of a target land, a relationship between an underground depth of the land and an oxygen concentration in soil. A second estimation function unit estimates, on the basis of a corrosion rate or a corrosion amount of a target metal near a ground surface of the land and the relationship estimated by the first estimation function unit, a relationship between the underground depth and the corrosion rate or the corrosion amount in the land from a relationship between the oxygen concentration and the corrosion rate or the corrosion amount. A third estimation function unit estimates a corrosion state of a structure constituted of the metal buried in target ground in the land from the relationship estimated by the second estimation function unit.
