PROBLEM TO BE SOLVED: To provide a surface treated aluminum plate capable of preventing deterioration of an exposed part even if a coating is removed by laser irradiation, and a manufacturing method therefor, and also to provide a surface-treated aluminum structure and a manufacturing method therefor.SOLUTION: A surface-treated aluminum plate 10 includes an aluminum plate 3, and a coating 2 formed at least on one surface of the aluminum plate 3. The total amount of components Si, Fe, Cu, Mn, Mg, Cr, Zn and Ti included in the coating 2 is 0.05 g/mor less. Part of the coating 2 is removed by a laser to expose a surface 3s of the aluminum plate 3 to use.SELECTED DRAWING: Figure 1 |
