Therefore, the content of the powder B is preferably 1 to 12 parts by weight. Further, the content of the powder B is 1 to 3 parts by weight or 6 to
In the case of 12 parts by weight, the hardness and adhesion strength of the film are further increased, and the wear resistance and the adhesion of the film are particularly excellent.

Thereby, it is possible to prevent peeling of the film in a cylinder having a small bore diameter and chipping of the film in a portion where the shape such as the upper end portion and the lower end portion of the cylinder changes rapidly. In addition, the hardness of the film is increased, and a high-quality film having excellent wear resistance can be obtained in combination with the improvement of the adhesion strength.
