Zusammenfassung:	To provide a surface treated aluminum plate having corrosion resistance, machining followability and resin adhesion.SOLUTION: A surface treated aluminum plate includes an aluminium base material and a surface treated layer formed on at least one surface of the aluminium base material. The aluminium base material is an aluminium plate or an aluminium alloy plate; the surface treated layer includes aluminium hydroxide; and in an infrared absorption spectrum measured by FT-IR, when defining an absorbance peak height in a wave number of 850-1000 cm-1 as Pa and defining an absorbance peak height in a wave number of 1000-1200 cm-1 as Pb, the value of Pa/Pb is 6.0 or less.SELECTED DRAWING: Figure 1 【課題】耐食性、加工追従性、及び、樹脂密着性を兼ね備えた表面処理アルミニウム板を提供する。【解決手段】アルミニウム基材と、前記アルミニウム基材の少なくとも一方の面に形成された表面処理層と、を含み、前記アルミニウム基材が、アルミニウム板、又はアルミニウム合金板であり、前記表面処理層が、水酸化アルミニウムを含み、ＦＴ－ＩＲで測定される赤外吸収スペクトルにおいて、波数８５０～１０００ｃｍ－１の吸光度ピークの高さをＰａと定義し、波数１０００～１２００ｃｍ－１の吸光度ピークの高さをＰｂと定義したとき、Ｐａ／Ｐｂの値が６．０以下である、ことを特徴とする、表面処理アルミニウム板。【選択図】図１
