The invention relates to an apparatus which is composed of absorptive fillers for collecting samples for clinical diagnosis and analysis. The component of the invention comprises a rod whose ends are covered with the absorptive fillers which is made from fibrous material with hydrophile property for easy absorbing the samples. The invention is characterized in that the layered and brush-shaped fiber is covered on the ends of the rod; the brushed fiber layer is formed in an electrostatic field, that is to say, the fiber is deposited to be formed in certain directions on the ends of the rod under the action of the electrostatic field.
