Abstract

The present disclosure relates to a resin composition for coating an optical fiber, the resin composition including: a base resin that contains an oligomer, a monomer, and a photopolymerization initiator; and inorganic oxide particles, in which the inorganic oxide particles include a plurality of particle groups having different volume average particle sizes, and the volume average particle size is measured by small-angle X-ray scattering.
