Wiring member and method for manufacturing wiring member

The purpose of the present invention is to provide a technique capable of easily suppressing the entry of a resin into a chamber. A wiring member (10) is provided with: a connector housing (20) in which a chamber (21) is formed; an electric wire (30), one end of which is housed in the chamber and the other end of which extends outward from the opening of the chamber; a sealing member (40) that is attached to the connector housing or the electric wire and blocks at least a part of a gap between the connector housing and the electric wire at the opening of the chamber; and a resin molded portion (50) covering from a rear end portion of the connector housing to a position of an intermediate portion of the electric wire closer to the other end portion side than a portion where the sealing member is provided. 目的在于提供一种能够简易地抑制树脂向腔室的进入的技术。配线构件(10)具备：连接器壳体(20)，形成有腔室(21)；电线(30)，该电线的一端部收容于所述腔室，并且该电线的另一端部从所述腔室的开口部向外侧延伸出；密封部件(40)，装配于所述连接器壳体或所述电线，将所述腔室的所述开口部处的所述连接器壳体与所述电线之间的间隙的至少一部分闭塞；及树脂成形部(50)，从所述连接器壳体的后端部覆盖至所述电线中的比设置有所述
