PROBLEM TO BE SOLVED: To provide a manufacturing method of a bar-like component, and the bar-like component in which a manufacturing cost can be reduced while positioning accuracy of a pipe made of carbon fiber-reinforced resin and a metal component is improved in the case of constituting a bar-like component by connecting the pipe and the metal component.SOLUTION: A bar-like component 22 has a pipe 10, and body parts 20 and extension parts 21 which are arrayed in an axial direction X of the pipe 10, and the extension parts 21 include metal components 17, 18 connected to the pipe 10 from the axial direction X. A manufacturing method of the bar-like component 22 includes: a process of winding a prepreg sheet 26 impregnated with resin 28 to a core material, which is constituted by connecting a mandrel to the extension part 21 having an outer peripheral surface 21A to which surface roughening is applied, in the axial direction X; a process of forming the pipe 10 which is externally fixed to the outer peripheral surface 21A by burning and hardening the prepreg sheet 26 wound to the core material; and a process of removing the mandrel from the pipe 10.

    【課題】炭素繊維強化樹脂製のパイプと金属部品とを連結することでバー状部品を構成する場合において、パイプと金属部品との位置決め精度を向上させつつ、製造コストの低減を図ることができるバー状部品の製造方法、および、当該バー状部品を提供すること。【解決手段】バー状部品22は、パイプ10と、パイプ10の軸方向Xに並ぶ本体部20および延長部21を有し、延長部21がパイプ10に対して軸方向Xから連結される金属部品17、18とを含む。バー状部品22の製造方法は、マンドレルと、粗面加工が施された外周面21Aを有する延長部21とを軸方向Xにつなげることによって構成される芯材に樹脂28を含浸させたプリプレグシート26を巻き付ける工程と、芯材に巻き付けられたプリプレグシート26を焼成硬化させることで外周面21Aに対して外嵌固定されたパイプ10を形成する工程と、マンドレルをパイプ10から取り除く工程とを含む。【選択図】図4
