<p>A multilayer material, including a multilayer portion which includes: at least two kinds of compound layers having different compositions from each other, each of which mainly comprises: at least one kind of element (first element) selected from the Group IVa elements, Group Va elements, and Group VIa elements in the Periodic Table, and Al, Si, C and B; and at least one kind of element (second element) selected from B, C, N and O; and a composition-modulated layer disposed between the compound layers, and having a composition such that the composition ratio (at%) of an element is changed. In the above multilayer material, the compound layer and the composition-modulated layer are periodically stacked, and the multilayer portion has a crystal lattice which is continuous during at least one period between respective layers constituting the multilayer portion.</p> |
