The water repellent agent is dissolved in a supercritical fluid such as, a supercritical COfluid, as a solvent to provide at least the component main body with water repellency. After providing the water repellency, the water repellent agent on the outer surface of the component main body is removed. As the water repellent agent, a silane coupling agent may be used.
