To provide: a tubular electric wire protection member in which, upon preparation of a wire harness, an electric wire can easily be inserted into a hollow part thereof; and a wire harness which is excellent in shape holding properties when adding deformation such as bending and has no electric wire protruding due to deformation.SOLUTION: The electric wire protection member has a structure in which a tubular shape is obtained by winding a sheet material containing polyvinyl chloride, a plasticizer, an elastomer and an inorganic filler in a peripheral direction, and an inside end and an outside end in the peripheral direction overlap with each other in a diameter direction. Content ratios of the plasticizer, the elastomer and the inorganic filler are 25 to 75 mass parts, 1 to 15 mass parts and 8 mass parts or less to 100 mass parts of the polyvinyl chloride, respectively.SELECTED DRAWING: Figure 1
【課題】管状の電線保護部材であって、ワイヤーハーネスの作製の際に、その空洞部に電線を容易に挿通させることができる電線保護部材、及び、曲げ等の変形を加えた場合の形状保持性に優れ、変形により電線がはみ出すことのないワイヤーハーネスを提供する。【解決手段】本発明は、ポリ塩化ビニルと、可塑剤と、エラストマーと、無機充填剤とを含有するシート材が周方向に巻かれて管状をなし、周方向の内側の端部と外側の端部とが径方向に相互に重なった構造を有する電線保護部材であって、可塑剤、エラストマー及び無機充填剤の含有割合がポリ塩化ビニル100質量部に対して、それぞれ、25〜75質量部、1〜15質量部、及び、8質量部以下である。【選択図】図1
