Abstract: A method is provided that forms a solid film on a bearing component of a rolling bearing. A solution containing a fluorine compound and a lubricant having no functional group is allowed to adhere to the bearing component as a first liquid film (adhesion step). The adhering first liquid film is hardened to form the solid film on the bearing component. The rolling bearing including the bearing component with the solid film formed thereon is rotated. The rolling bearing is washed in a washer fluid containing the same lubricant as that used in the adhesion step, and the washer fluid is allowed to adhere to the bearing component as a second liquid film. Then, the adhering second liquid film is dried.
