This optical fiber strand is provided with a glass fiber and a coating resin layer that covers the glass fiber. The coating resin layer contains tin and a cured product of an ultraviolet curable resin composition that contains, as a photoinitiator, 2, 4, 6-trimethylbenzoyl diphenylphosphine. The ratio of uncured components having a molecular weight of 1,000 or less in the coating resin layer is 15% by mass or less. The ratio of the amount of a phosphorus-tin complex to the amount of carbon hydride in the surface of the coating resin layer is 1,000 ppm or less.
