PROBLEM TO BE SOLVED: To provide a method of estimating corrosion rate and a corrosion rate estimating device for estimating the corrosion rate in a gap of a metal.;SOLUTION: The corrosion rate estimating device includes a test material 11, where two metal plates of which an insulation film on one surface has been removed are disposed at a prescribed interval so that one surface of one metal plate mutually faces that of the other metal plate; an electrochemical impedance measuring means 12 of acquiring the impedance of the test material from the response of an electric signal applied between the metal plates of the test material 11; and a calculation means 13 of calculating the polarization resistance of the metal plates, from the impedance of the test material 11 acquired by the electrochemical impedance measuring means 12.;COPYRIGHT: (C)2011,JPO&INPIT
