Abstract
A tubular bodyincludes a layer containing a resin and conductive particles, the layer having a first regionC that is free of conductive particles and lies at the outermost surface, and a second regionB that has higher conductivity than other regions and lies closer to the innermost surface than the first region. A coating film of a coating liquid containing the conductive particles and resin material is dried, and then an eluting solvent for eluting the resin material from the film is applied thereto. As a result of this, the conductive particles are localized in the coating film at the side coated with the eluting solvent. Thereafter, upon drying the eluting solvent, the resin material dissolved in the eluting solvent deposits on the region where the conductive particles are localized, whereby a particle-free resin region free of the conductive particles is formed.
