PROBLEM TO BE SOLVED: To provide rust-prevention treatment liquid capable of suppressing haloing by improving adhesiveness between a metal not subjected to a roughening treatment or subjected to a low-roughening treatment and an insulation resin layer, and by improving chemical resistance to an agent such as a plating solution.SOLUTION: There is provided rust-prevention treatment liquid used jointly with specific surface treatment liquid used for a metal, which is rust-prevention treatment liquid having at least one kind of azole compound shown by some of formulas (1) to (4) (R-Rare each independently H, an amino group, a mercapto group, a C1-3 alkyl group or a C1-3 alkylthio group).SELECTED DRAWING: None 【課題】粗化処理をしない又は低粗化処理される金属と絶縁樹脂層との接着性を高め、めっき液等の薬剤に対する耐薬品性を向上させてハローイングを抑制できる防錆処理液の提供。【解決手段】金属に用いられる特定表面処理液と併用する防錆処理液であって、式（１）〜（４）のいずれかで示されるアゾール化合物を少なくとも１種含有する防錆処理液。（Ｒ１〜Ｒ１１は夫々独立して、Ｈ、アミノ基、メルカプト基、Ｃ１〜３のアルキル基又はＣ１〜３のアルキルチオ基）【選択図】なし
