Abstract: A manufacturing method for the cylindrical laminated body includes superimposing application step, a solvent removal step and an imidization step. In the superimposing application step, a coating material containing fluororesin particles and a polyimide precursor solution are applied in a superimposing manner on a core body. In the solvent removal step, the solvent is removed from the coating material and the polyimide precursor solution. In the imidization step, the polyimide precursor is imidized along with the formation of the coating material into a covering film.

Abstract: A tubular article (31) is provided by molding and thermosetting a mixture including polyimide and fluororesin particles. At least a part of the fluororesin particles present in the vicinity of a surface layer of the tubular article (31) is melt-flowed into the outer face or both faces of the tubular article and oozes out so as to form a fluororesin coating partially or entirely. The tubular article (31) can be manufactured by applying on the outer face of a mold a dispersion prepared by adding fluororesin particles to a polyimide precursor solution and casting to have a predetermined thickness, heating for imidization so that the maximum temperature for the imidization is set higher than the melting point of the fluororesin, cooling and subsequently separating the tubular article from the mold. The present invention provides a tubular article with low dynamic friction coefficient particularly for the outer face, with high durability and that can be manufactured at low cost, and a method of manufacturing the tubular article.
