PROBLEM TO BE SOLVED: To provide a covered electric wire with a terminal, capable of inhibiting the corrosion of an electrical contact part; a manufacturing method thereof; and a wire harness.SOLUTION: A terminal fitting 5 formed from a component 9 cut out in a prescribed spread shape of a terminal from a plated metal plate 8 of copper based metal is used. The exposed copper based metal part at the cross section is pretreated with a pretreatment agent including at least one selected form a rust inhibitor, a binder resin, a silane coupling agent, and alkoxy silane. A covered electric wire 2 includes an electric wire conductor 3 covered with an insulator 4. The electric wire conductor 3 is connected to the terminal fitting 5. The contact part 6 between the terminal fitting 5 and the electric wire conductor 3 is covered with a corrosion inhibitor 7. A covered electric wire 1 with a terminal is thus obtained. 【課題】電気接触部の腐食を抑制可能である端子付き被覆電線、その製造方法及びワイヤーハーネスを提供する。【解決手段】銅系金属にめっきが施された金属板８を所定の端子展開形状に切断した部材９から形成された端子金具５を用い、切断面の銅系金属露出部に、防錆剤、バインダー樹脂、シランカップリング剤、アルコキシシランから選択される少なくとも１種を含む前処理剤を用いて前処理を施した後、端子金具５に電線導体３が絶縁体４で被覆された被覆電線２の電線導体３を接続し、端子金具５と電線導体３の接触部６を防食剤７により被覆して端子付き被覆電線１を得た。【選択図】図１
