To provide a timepiece component capable of suppressing chipping of silicon base and a weight increase.SOLUTION: An escape wheel (one example of timepiece components) includes: a silicon base including an insertion part into which a shaft member is inserted; and a film formed on a contact part which contacts at least with the shaft member on a surface of the base. The film contains metal alkoxide having fluorine atoms.SELECTED DRAWING: Figure 6 【課題】シリコン製の基体のチッピングを抑制でき、重量増加も抑制できる時計用部品を提供すること。【解決手段】ガンギ歯車部（時計用部品の一例）は、軸部材が挿通される挿通部を有するシリコン製の基体と、基体の表面のうち、少なくとも軸部材と当接する当接部に形成された被膜と、を有し、被膜は、フッ素原子を有する金属アルコキシドを含む。【選択図】図６
