Zusammenfassung:	To provide an aluminum member with excellent drainage, a fin for a heat exchanger, a tube, a header tank, and a heat exchanger.SOLUTION: An aluminum member of the present invention has a plurality of glass-based hydrophilic inorganic films of a SiO2 content of 60% or less in a scattered manner on a surface, where the number density is 2000 pieces/mm2 or more. In the aluminum member of the present invention, it is preferable that a coverage of the surface by the hydrophilic inorganic films be 0.5% or more and 70% or less.SELECTED DRAWING: Figure 1 【課題】本発明は、排水性に優れるアルミニウム部材、熱交換器用フィン、チューブ、ヘッダータンク及び熱交換器の提供を目的とする。【解決手段】本発明のアルミニウム部材は、表面にＳｉＯ２含有量６０％以下のガラス系の親水性無機皮膜が複数点在されており、その数密度が２０００個／ｍｍ２以上であることを特徴とする。本発明のアルミニウム部材は、前記親水性無機皮膜による前記表面の被覆率が０．５％以上７０％以下であることが好ましい。【選択図】図１
