Provided is an aluminum fin material which suppresses a decrease in hydrophilicity due to heating and which has excellent heat resistance. An aluminum fin material (10) has an aluminum plate (1) and a film layer (2), the film layer (2) has a hydrophilic film layer (2b) and a lubricating film layer (2c) in this order from the aluminum plate (1) side, and the lubricating film layer (2c) comprises: a resin matrix containing polyethylene glycol as a main component; the hydrophilic component contains at least one of a sulfonic acid group and an ester group, and the change in the amount of functional groups contributing to hydrophilicity before and after the hydrophilic component is heated at 200 DEG C for 10 minutes is 15% or less. The coating layer (2) may further have a corrosion-resistant coating layer (2a). 提供一种铝制翅片材，抑制加热造成的亲水性降低，耐热性优异。铝制翅片材(10)具有铝板(1)和皮膜层(2)，皮膜层(2)，从铝板(1)侧起，按顺序具有亲水性皮膜层(2b)和润滑性皮膜层(2c)，润滑性皮膜层(2c)包括：含有聚乙二醇作为主要成分的树脂基体；含磺酸基和酯基中的至少一方的亲水性成分，亲水性成分，在200℃、10分钟的条件下进行加热前后的有助于亲水性的官能团量的变化为15％以下。还有，皮膜层(2)可以
