PROBLEM TO BE SOLVED: To provide a crack evaluation method capable of evaluating cracks occurring on a sample surface such as a coated steel sheet.SOLUTION: The crack evaluation method is used for evaluating cracks occurring on a sample surface. The method includes the steps of: depositing a metal film on the sample surface; acquiring a reflection electron image (BSE image) of the metal thin film by using a scanning electron microscope (SEM); and evaluating the cracks on the basis of the acquired BSE image. |
