description To provide a tubular member including an insulating layer with high quality.SOLUTION: The present invention discloses a method of manufacturing a tubular member for an exhaust gas treatment device, the tubular member including a tubular body made of a metal and an insulating layer formed on at least an inner peripheral surface of the tubular body, the insulating layer containing glass. The method includes steps of: forming a coating film by spraying coating liquid for insulating layer formation onto the inner peripheral surface of the tubular body; and firing the coating film to obtain the insulating layer. The spraying is performed while the tubular body is rotated with its length direction as a rotation axis.SELECTED DRAWING: Figure 1 【課題】品質に優れた絶縁層を有する筒状部材を提供すること。【解決手段】金属製の筒状本体と前記筒状本体の少なくとも内周面に設けられたガラスを含む絶縁層とを有する排ガス処理装置用筒状部材の製造方法であって、前記筒状本体の内周面に、絶縁層形成用塗工液を噴霧して塗膜を形成する工程と、前記塗膜を焼成して前記絶縁層を得る工程と、を含み、前記噴霧は、前記筒状本体をその長さ方向を回転軸にして回転させながら行われる。【選択図】図1
