PROBLEM TO BE SOLVED: To provide a surface treated aluminum plate excellent in weldability, 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 containing C, O, N and H, formed at least on one surface of the aluminum plate 3. Each amount of components Mg, Cu, Zn and Si included in the coating 2 is 5 g/mor less and the total amount of the components is 0.05-5 g/m. 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 【課題】溶接性に優れた表面処理アルミニウム板及びその製造方法、並びに、表面処理アルミニウム構造体及びその製造方法を提供する。【解決手段】本発明に係る表面処理アルミニウム板１０は、アルミニウム板３と、前記アルミニウム板３の少なくとも一方の面に形成したＣ、Ｏ、Ｎ、Ｈを含む皮膜２と、を備え、前記皮膜２中に含まれるＭｇ、Ｃｕ、Ｚｎ、Ｓｉのそれぞれの含有量が５ｇ／ｍ２以下、且つこれらの成分の合計量が０．０５〜５ｇ／ｍ２であり、前記皮膜２の一部をレーザにより除去してアルミニウム板３の表面３ｓを露出させて使用されることを特徴とする。【選択図】図１
