Zusammenfassung:	To provide a combination of a tube and a fin with excellent drainage of water droplets condensed on an aluminum fin, and a heat exchanger.SOLUTION: A tube for a heat exchanger is made of aluminum or an aluminum alloy, in which a refrigerant is flowed, and a water contact angle is less than 30° on the outside. A tube for a heat exchanger made of aluminum or an aluminum alloy and connected to a fin having a water contact angle higher than the water contact angle of the tube by 5° or more to form a heat exchanger.SELECTED DRAWING: Figure 1 【課題】本発明は、アルミニウムフィンに結露した水滴の排水性に優れるチューブとフィンの組合せおよび熱交換器の提供を目的とする。【解決手段】本発明に係るチューブは、アルミニウム又はアルミニウム合金からなり、内部に冷媒が流され、外側の水接触角が３０°未満である熱交換器用チューブであって、アルミニウム又はアルミニウム合金からなり、前記チェーブの水接触角よりも５°以上高いフィンと接続されて熱交換器を構成するための熱交換器用チューブである。【選択図】図１
