PURPOSE: To easily make the surface of a synthetic resin conductive even when the shape thereof is complicated by bringing a synthetic resin molded body into contact with a solution of ferric chloride in a specific solvent and subsequently exposing the surface to pyrrole or the like.
CONSTITUTION: Ferric chloride anhydride or ferric chloride hydrate is dissolved in a solvent, wherein surface tension is 35dyn/cm or less at 25°C and solubility of ferric chloride anhydride or ferric chloride hydrate is 1.0wt.% or more at 25°C, in an amount of 1.0wt.% or more. A synthetic resin molded body composed of nylon or modified PPO is brought into contact with this solution and, thereafter, the surface of this synthetic resin molded body is exposed to pyrrole, thiophene, furan or a derivative thereof. By this method, even when spray is difficult because of the complicated shape of a synthetic resin, the surface of the synthetic resin can be easily made conductive.
