A fiber guide having an excellent wear resistance against a high-functional chemical fiber is provided. A fiber guide of the invention includes ceramics containing at least crystal grains of zirconium oxide, an average crystal grain diameter of a crystal grain constituting the ceramics being 1 µm or smaller. Since this fiber guide which complies with the above configuration has an excellent wear resistance against a high-functional chemical fiber, it is possible to reduce a replacement frequency of the fiber guide, and improve the production efficiency. |
