PROBLEM TO BE SOLVED: To provide a water cut-off structure for a waterproof connector and an electric wire with a terminal, capable of reducing the number of molding dies for mold-forming a water cut-off part and securing contact reliability between terminals.SOLUTION: A water cut-off structure for a waterproof connector 11 includes: an electric wire 17 in which the periphery of a conductor 21 is covered with an insulating coating 23; a terminal 13 in which an electric contact part 25 in electrical contact with a mating terminal and an electric wire connection part 30 electrically connected to the conductor 21 of a terminal of the electric wire 17 are formed; a housing 19 in which the terminal 13 mounted at the terminal of the electric wire 17 is housed in a terminal housing chamber 43 and the electric wire 17 is led out to the outside 53 from a wire lead-out hole 51; and a waterproof part 15 which is molded in an outer peripheral portion of the terminal of the electric wire 17 and water-tightly seals between the electric wire 17 and the electric wire leading-out hole 51. 【課題】防水部をモールド成形する成形金型を削減でき、端子間の接触信頼性を確保できる防水コネクタの止水構造及び端子付電線を提供する。【解決手段】防水コネクタ１１の止水構造は、導体２１の周囲が絶縁性の被覆２３によって覆われる電線１７と、相手端子と電気的に接触する電気接触部２５と電線１７の端末の導体２１と電気的に接続される電線接続部３０とが形成される端子１３と、電線１７の端末に取り付けられた端子１３が端子収容室４３に収容されて電線１７が電線導出穴５１から外部５３へ導出されるハウジング１９と、電線１７の端末の外周部分に立体造形によって成形され、電線１７と電線導出穴５１との間を水密にシールする防水部１５と、を備える。【選択図】図１
