A rolling sliding part is in relative rolling contact or sliding contact with a companion member, and is formed on a contact surface thereof with a lubricating film (5) composed of a polymer which contains fluorine with a functional group and in which particles (6) of polytetrafluoroethylene resin are dispersed and mixed. The lubricating film (5) exhibits a favorable lubricating property and generates little dust, and the particles (6) mixed in the film provide a favorable cushioning action under loading. As the lubricating film (5) itself and the particles (6) are fluorine based, they provide for a good compatibility therebetween.
