Abstract: A process for coating the inner wall surface of a thin tube having an inside diameter of 0.2 to 5 mm with a resin. The tube is first filled with a resin particulate dispersion. The dispersion filling the tube is held therein by its surface tension and does not flow out. A heater is positioned about the upper end of the tube and is moved down toward its lower end to heat the tube and thereby cause minute resin particles to adhere to its inner wall surface. Then, the tube is heated in a furnace and is cooled to have its inner wall surface coated with the resin.
