PROBLEM TO BE SOLVED: To restrain any dust generation and improve a lubrication property and achieve a long life in a rolling bearing. SOLUTION: A solid film 5 of polyurethane high polymer compound containing fluorine is formed on the at least one of the constitution elements (inner/outer rings 1, 2, rolling bodies 3 and a retainer 4) of a rolling bearing. As this solid film 5 of polyurethane high polyner compound containing fluorine, whose molucule is urethane combination, is formed in a three dimensional netting structure, wear in addition to peeling off and lack is restrained. |
