PROBLEM TO BE SOLVED: To provide a polyimide tubular molding in which interfacial disorder between polyimide layers is suppressed, in the polyimide tubular molding having a laminated structure. SOLUTION: The polyimide tubular molding has a first layer containing a polyimide resin and a chemical compound which promotes imide-reaction, and a second layer which contains a polyimide resin and is formed on the first layer.
