PROBLEM TO BE SOLVED: To provide a wiring harness capable of downsizing a housing through which a shield wire is inserted.SOLUTION: A wiring harness 1 comprises: a shield wire 2 including a wire body 20 configured by covering a conductor with an insulator and a braided shield 23 provided in an outer periphery of the wire body 20; a housing 3 including a small diameter cylindrical part 301 through which the wire body 20 that is not covered with the braided shield 23 is inserted, and a large diameter cylindrical part 302 in which a part of the shield wire 2 including an end portion of the braided shield 23 is accommodated; an annular retainer 4 interposed between an inner peripheral surface of the large diameter cylindrical part 302 and an outer peripheral surface of the wire body 20 exposed form the braided shield 23; and an O ring 5 in elastic contact with the inner peripheral surface of the large diameter cylindrical part 302 and the outer peripheral surface of the wire body 20. The O ring 5 is disposed between a step surface 303a that is between the large diameter cylindrical part 302 and the small diameter cylindrical part 301, and the retainer 4, and bending of the wire body 20 inside of the O ring 5 is restricted by the retainer 4.SELECTED DRAWING: Figure 1 【課題】シールド電線を挿通させるハウジングの小型化が可能なワイヤハーネスを提供する。【解決手段】ワイヤハーネス１は、導体を絶縁体で被覆してなる電線本体２０、及び電線本体２０の外周に設けられた編組シールド２３を有するシールド電線２と、編組シールド２３に覆われていない電線本体２０を挿通させる小径筒状部３０１、及び編組シールド２３の端部を含むシールド電線２の一部を収容する大径筒状部３０２を有するハウジング３と、大径筒状部３０２の内周面と編組シールド２３から露出した電線本体２０の外周面との間に介在する環状のリテーナ４と、大径筒状部３０２の内周面及び電線本体２０の外周面に弾接するＯリング５と、を備え、Ｏリング５は、大径筒状部３０２と小径筒状部３０１との間の段差面３０３ａとリテーナ４との間に配置され、Ｏリング５の内側における電線本体２０の撓みがリテーナ４によって規制される。【選択図】図１
