Coating of the surface of a pencil barrel with a coat film having a sufficient thickness and smoothness can be well achieved by using a hot-melt polyester as a coating material. The formation of the desired coat film on the pencil barrel can be attained even by only a single coating operation. The coat film of hot-melt polyester formed on the surface of the pencil barrel has an excellent affinity for and an improved adhesion to not only a pencil barrel but also to a lacquer if any lacquer is additionally coated on the polyester-coated pencil barrel. Any organic solvent need not be used, and the coating operation can be completed in an extremely short time. Therefore, the method of the present invention is very advantageous from the viewpoints of prevention of environmental pollution and enhancement of productivity.
