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.
