Abstract
A method of producing an optical fiber, containing: (a) a resin application step of applying an ultraviolet curable resin, onto an outer circumference of an optical fiber; (b) a heating step of heating the ultraviolet curable resin; and (c) a light irradiation step of irradiating the ultraviolet curable resin with ultraviolet light emitted from a semiconductor light emitting element, in a state in which the ultraviolet curable resin is heated, to cure the ultraviolet curable resin into a coating resin.
