Summary:A method for evaluating a structure is disclosed, the structure including a base material containing at least one kind of metal selected from the group consisting of hydrogen storage metals and hydrogen storage alloys, an intermediate layer provided on the base material and stacked alternately with a first layer containing low work function substances relatively lower in work function than the metal and a second layer containing the metal, and a surface layer provided on the intermediate layer and containing the metal, wherein the method includes measuring a change in polarization between incident light and reflected light by irradiating the surface layer with light, while holding the structure at a predetermined temperature, and comparing a measurement value of the change in polarization with a threshold of a change in polarization of a structure prepared in advance and evaluating a soundness of the structure based on comparison results.
