Beschreibung
Zusammenfassung:	An optical fiber comprises a glass fiber comprising a core and a cladding, and a coating resin layer covering the outer periphery of the glass fiber, wherein the coating resin layer has a primary resin layer being in contact with the glass fiber and covering the glass fiber and a secondary resin layer covering the outer periphery of the primary resin layer, the secondary resin layer comprises hydrophobic spherical silica particles, and the content of the silica particles is 7% by mass or more and 60% by mass or less based on the total amount of the secondary resin layer, and the absolute value of the surface potential of the optical fiber is 10 mV or more and 60 mV or less.
