The braided member has a cylindrical part that covers the outer periphery of the electric wire, and a ground wire that is collected from an end of the cylindrical part, extends separably from the electric wire, and is connected to a ground terminal. The ground terminal is then connected to a ground member such as a vehicle body or a metal casing, for example. In such a wire harness, for example, noise radiation from the electric wire is suppressed by the braided member.

　同構成によれば、ホルダは、アース線における延在方向の一部を保持するアース線保持部を有するため、アース線の経路が規制される。これにより、電線に対するアース線の位置をより一層安定化させることができる。このため、編組部材の筒状部から接地部材に接続されるアース端子までのインピーダンスがより一層安定する。よって、シールド性能がより安定する。 According to the same configuration, since the holder has a ground wire holding portion that holds a part of the ground wire in the extending direction, the path of the ground wire is regulated. Thereby, the position of the ground wire with respect to the electric wire can be further stabilized. Therefore, the impedance from the cylindrical portion of the braided member to the ground terminal connected to the ground member is further stabilized. Therefore, shielding performance becomes more stable.

According to this configuration, since the holder has a mounting portion that can be attached to a harness attachment target, the route of the wire harness can be regulated without using a separate member. That is, the configuration can be simplified compared to the case where the holder and the route regulating member for regulating the route of the wire harness are provided separately.

　電線１２は、編組部材１３の筒状部１３ａに覆われる。編組部材１３のアース線１３ｂが設けられる位置には、ホルダ１６が設けられる。ホルダ１６は、電線１２に対して取り付けられる。アース線１３ｂに接続されるアース端子１５は、ホルダ１６の弾性保持部１６ｃに保持される。そして、アース端子１５は接地部材２１に接続される。これにより、電線１２からのノイズの放射は、編組部材１３によって良好に抑制される。 Next, the operation of the wire harness 11 configured as described above will be explained.
The electric wire 12 is covered by the cylindrical portion 13a of the braided member 13. A holder 16 is provided at a position of the braided member 13 where the ground wire 13b is provided. The holder 16 is attached to the electric wire 12. The ground terminal 15 connected to the ground wire 13b is held by an elastic holding portion 16c of the holder 16. Then, the ground terminal 15 is connected to the ground member 21. As a result, noise radiation from the electric wire 12 is effectively suppressed by the braided member 13.
　次に、上記第１実施形態の効果を以下に記載する。
　（１）電線１２に取り付けられるホルダ１６を備え、ホルダ１６はアース端子１５を保持する弾性保持部１６ｃを有するため、電線１２に対するアース端子１５の位置が安定する。これにより、電線１２に対するアース線１３ｂの位置を安定化させることができる。このため、編組部材１３の筒状部１３ａから接地部材２１に接続されるアース端子１５までの間のインピーダンスが安定する。よって、ワイヤハーネス１１のシールド性能が安定する。 Next, the effects of the first embodiment will be described below.
(1) Since the holder 16 is provided to be attached to the electric wire 12 and the holder 16 has an elastic holding portion 16c that holds the ground terminal 15, the position of the earth terminal 15 with respect to the electric wire 12 is stabilized. Thereby, the position of the ground wire 13b with respect to the electric wire 12 can be stabilized. Therefore, the impedance between the cylindrical portion 13a of the braided member 13 and the ground terminal 15 connected to the ground member 21 is stabilized. Therefore, the shielding performance of the wire harness 11 is stabilized.
　（２）ホルダ１６は、電線１２の外側から電線１２に取り付け可能に構成されることで、例えば、環状のホルダに予め電線１２を通しておくといった必要がないため、組み付け性が良好となる。 (2) Since the holder 16 is configured so that it can be attached to the electric wire 12 from the outside of the electric wire 12, for example, there is no need to pass the electric wire 12 through the annular holder in advance, which improves ease of assembly.
　（３）スリット１６ｂが広がるようにホルダ筒部１６ａを撓ませた状態で、スリット１６ｂからホルダ筒部１６ａの内部に電線１２を挿入することで、電線１２の外側から電線１２にホルダ１６を容易に取り付けることができる。 (3) By inserting the electric wire 12 into the holder cylinder part 16a from the slit 16b while bending the holder cylinder part 16a so that the slit 16b widens, the holder 16 can be easily attached to the electric wire 12 from the outside of the electric wire 12. It can be attached to.
　（４）アース端子１５を保持する保持部は、アース端子１５を弾性によって保持する弾性保持部１６ｃである。よって、弾性によって弾性保持部１６ｃにアース端子１５を容易に保持させることができる。 (4) The holding part that holds the ground terminal 15 is an elastic holding part 16c that holds the ground terminal 15 with elasticity. Therefore, the elastic holding portion 16c can easily hold the ground terminal 15 due to its elasticity.
　（５）ホルダ１６は、アース線１３ｂにおける延在方向の一部を保持するアース線保持部としてのアース線弾性保持部１６ｄを有するため、アース線１３ｂの経路が規制される。これにより、電線１２に対するアース線１３ｂの位置をより一層安定化させることができる。このため、編組部材１３の筒状部１３ａから接地部材２１に接続されるアース端子１５までのインピーダンスがより一層安定する。よって、ワイヤハーネス１１のシールド性能がより安定する。 (5) Since the holder 16 has the ground wire elastic holding portion 16d as a ground wire holding portion that holds a part of the ground wire 13b in the extending direction, the path of the ground wire 13b is regulated. Thereby, the position of the ground wire 13b with respect to the electric wire 12 can be further stabilized. Therefore, the impedance from the cylindrical portion 13a of the braided member 13 to the ground terminal 15 connected to the ground member 21 is further stabilized. Therefore, the shielding performance of the wire harness 11 becomes more stable.
　（６）アース線１３ｂを保持するアース線保持部は、アース線１３ｂにおける延在方向の一部を弾性によって保持するアース線弾性保持部１６ｄである。よって、弾性によってアース線弾性保持部１６ｄにアース線１３ｂにおける延在方向の一部を容易に保持させることができる。 (6) The ground wire holding portion that holds the ground wire 13b is a ground wire elastic holding portion 16d that elastically holds a part of the ground wire 13b in the extending direction. Therefore, the ground wire elastic holding portion 16d can easily hold a portion of the ground wire 13b in the extending direction due to its elasticity.
　（７）ホルダ１６は、樹脂製であるため、例えば、溶接された金属製のホルダに比べて、製造が容易となる。

　第２実施形態のワイヤハーネス３１は、第１実施形態のワイヤハーネス１１の構成の一部が異なる構成であるため、同様の構成については、同様の符号を付して、その詳細な説明は省略する。 (7) Since the holder 16 is made of resin, it is easier to manufacture than, for example, a welded metal holder.
