To provide a branch portion protection structure and a branch portion protection method capable of protecting a branch portion with a simple structure.SOLUTION: In a wire harness 10 inserted inside a main tubular protection member 20 and a branch tubular protection member 30 which have flexibility, a branch protection structure 1 for protecting a branch portion 13 in which a branch wire 12 is branched in a branch direction B from a main trunk line 11 having a plurality of bundled electric wires includes a main tubular protection member 20 through which the main trunk line 11 is inserted, and a branch tubular protection member 30 through which the wire 12 is inserted. At the branch portion 13, the branch wire 12 is led out from the main tubular protection member 20 in a branching direction B, and an end portion on the main trunk line 11 side of the branch tubular protection member 30 through which the branch line 12 extending in the branch direction B is inserted has a plurality of extension pieces 33, 33 formed by a plurality of branch main body side slits 32 extending in an axial direction L. The plurality of extension pieces 33, 33 are bent in different directions from the branch direction B along the main trunk line 11.SELECTED DRAWING: Figure 1 【課題】簡易な構造で分岐部を保護できる分岐部保護構造及び分岐部保護方法を提供すること。【解決手段】可撓性を有する主管状保護部材２０及び枝管状保護部材３０の内部に挿通されたワイヤーハーネス１０において、複数の電線が束ねられた主幹線１１から分岐方向Ｂに向かって枝線１２が分岐された分岐部１３を保護する分岐保護構造１は、主幹線１１が挿通する主管状保護部材２０と、枝線１２が挿通する枝管状保護部材３０とが備えられ、分岐部１３において枝線１２は、主管状保護部材２０から分岐方向Ｂに向かって導出され、分岐方向Ｂに向かって延出する枝線１２が挿通する枝管状保護部材３０の主幹線１１側の端部は、軸線方向Ｌに延びる複数の枝本体側スリット３２によって形成された複数の延出片３３，３３を有し、複数の延出片３３，３３は、主幹線１１に沿うように、分岐方向Ｂからそれぞれ異なる方向に曲げられている。【選択図】図１
