Abstract
A splicing structure of optical fibers in which optical fibers are coupled together, the optical fibers each comprising: a coated fiber portion including a glass fiber and a coating layer coating an outer periphery of the glass fiber; and a bare fiber portion where a certain length of the glass fiber is projected from an end face of the coating layer in an extending direction, wherein the glass fiber end faces of the bare fiber portion are fusion coupled together, and an outer periphery of the bare fiber portion is coated by a recoating layer, the recoating layer is a cured product of an ultraviolet light curable resin composition including a urethane (meth)acrylate oligomer and a mold release agent, and a content of the mold release agent is 0.01 to 1.5% by mass based on a total amount of the ultraviolet light curable resin composition.
