摘要：
A resin composition for coating an optical fiber is a resin composition comprising: a base resin containing an oligomer comprising urethane (meth)acrylate, a monomer, and a photopolymerization initiator; and hydrophobic zirconium oxide, wherein the content of the zirconium oxide is 0.5% by mass or more and 65% by mass or less based on the total amount of the resin composition.
