PROBLEM TO BE SOLVED: To provide a method for manufacturing a tubular body, capable of achieving uniform electrolytic polishing of the tubular body without irregularity by a simple method.SOLUTION: The method for manufacturing the tubular body includes at least one time of each of a step (a) and a step (b). In the step (a), an outer surface of the tubular body is electrolytically polished with an inner surface thereof being supported from the inside by an anode conductive member 13 in electrical contact with the tubular body. In the step (b), the inner surface of the tubular body is electrolytically polished with the outer surface thereof being supported from the outside by the anode conductive member in electrical contact with the tubular body.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】管状体の電解研磨において、簡易な方法により、ムラなく均一に電解研磨を達成できる管状体の製造方法を提供する。【解決手段】下記(a)工程および(b)工程を少なくとも1回以上含むことを特徴とする管状体の製造方法。(a)管状体と電気的に接触するアノード導電性部材13によって、管状体の内面を内側から支持して、管状体の外面を電解研磨する工程(b)管状体と電気的に接触するアノード導電性部材によって、管状体の外面を外側から支持して、管状体の内面を電解研磨する工程【選択図】図2
