    • A tubular body 101 includes a layer containing a resin and conductive particles 112, the layer having a first region 111C that is free of conductive particles and lies at the outermost surface, and a second region 111B 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.
    • 管状体101包括含有树脂的层和导电性粒子112,该层具有不具有导电粒子且位于最外表面的第一区域111C,以及比其他区域更高的导电率的第二区域111B 到最内表面比第一区域。 将含有导电性颗粒和树脂材料的涂布液的涂膜干燥,然后向其上涂布用于从树脂材料中洗脱的洗脱溶剂。 其结果是,导电粒子位于涂布有洗脱溶剂的一侧的涂膜中。 此后,在洗脱溶剂干燥后,溶解在洗脱溶剂中的树脂材料沉积在导电颗粒定位的区域上,由此形成不含导电颗粒的无颗粒树脂区域。
