To further enhance adhesion between an optical fiber and a resin tube.SOLUTION: An optical fiber carrier resin tube is provided, comprising a cylindrical resin tube 11, one or two or more optical fibers 12 lying in a cylinder wall 11A of the resin tube 11 and extending in a direction of a tube axis O1 of the resin tube 11, and adhesive sections 16 located at least partially between exterior surfaces of the optical fibers 12 and the resin tube 11. The adhesive sections 16 are formed of a cured product of an adhesive polyolefin resin composition. Preferably, the adhesive sections contain an acid-modified polyolefin resin.SELECTED DRAWING: Figure 2 【課題】光ファイバと樹脂管との接着力をより高める。【解決手段】円筒状の樹脂管１１と、前記樹脂管１１の筒壁１１Ａ内に位置し、前記樹脂管１１の管軸Ｏ１方向に延びる１本又は２本以上の光ファイバ１２と、前記光ファイバ１２の外面と前記樹脂管１１との間の少なくとも一部に位置する接着部１６と、を有し、前記接着部１６は、接着性ポリオレフィン樹脂組成物の硬化物であることよりなる。接着部は、酸変性ポリオレフィン樹脂を含むことが好ましい。【選択図】図２
