Abstract
A method for evaluating corrosion resistance of an aluminum sheet includes: preparing an aluminum sheet containing dissimilar metal particles in a matrix metal; creating an observation surface by treating a surface of the aluminum sheet with hydrochloric acid; observing a potential difference between the dissimilar metal particles and their surroundings by using an observation device; and evaluating corrosion resistance of the aluminum sheet from a product of the potential difference and the number of the dissimilar metal particles.
