<p>A coating structure (1, E) for a metal member (10) includes a surface-smoothing layer (11, 13, 14) formed on the metal member (10) for smoothing a surface of the metal member (10), and a fluorine-based film (12) formed on the surface-smoothing layer (11, 13, 14). The fluorine-based film (12) can be formed by applying a fluorine-containing solution (120) on the surface-smoothing layer (11, 13, 14), and by drying the fluorine-containing solution (120). The coating structure (1, E) can be suitably used for a fuel injection nozzle (7).</p> |
