A wire harness includes an electric wire, a braided conductor covering the electric wire, a grommet having a tubular insertion portion through which the electric wire and the braided conductor are inserted, a water stop sheet sandwiched between an inner peripheral surface of the insertion portion and the braided conductor, and a fixture attached to the insertion portion so as to reduce a diameter of the insertion portion. The water stop sheet includes a base material layer having a plurality of pores communicating with each other in a thickness direction of the water stop sheet and a sealing compound layer laminated on the base material layer. The sealing compound layer is deformed so as to enter gaps between thin conductor wires constituting the braided conductor and the pores of the base material layer.

Wire harness

An exterior end portion cap is configured to be attached to an electrically conductive path and an exterior member. The exterior end portion cap includes an external exposure portion having a first blocking portion, an internal insertion portion having a second block portion, and an electrically conductive path housing recess portion formed to extend across the external exposure portion and the internal insertion portion. The first blocking portion has a planar portion configured to abut against the exterior member. The second blocking portion has holding piece portions that are deformable to wind around the electrically conductive path circumferentially. The electrically conductive path housing recess portion is formed into a concave portion that is so deep that a part of an outer surface of the electrically conductive path is pressed against an inner surface of the exterior member.

Exterior end portion cap and wire harness

An exterior end portion cap is configured to be attached to electrically conductive paths and an exterior member. The exterior end portion cap includes an external exposure portion having a first blocking portion and an internal insertion portion having a second block portion. The internal insertion portion has a slit. The second blocking portion has a convex portion that is fitted to a gap between the electrically conductive paths. The exterior end portion cap is configured to be divided into two divided parts. The slit is disposed in a position corresponding to a position of a divided surface of the two divided parts and is formed so as to bring the part of the outer surfaces of the electrically conductive paths into contact with an inner surface of the exterior member near the end portion of the exterior member.
