A method of producing an optical fiber wire including a coating made of an ultraviolet curable resin, the method includes: a first irradiation step including applying first ultraviolet light to a point on the optical fiber wire where at least a portion of the ultraviolet curable resin is uncured; and a second irradiation step including applying second ultraviolet light to the point on the optical fiber wire where at least the portion is cured after the first irradiation step. The portion is a surface layer of the coating. A temperature of the optical fiber wire immediately before the second irradiation step is 50° C. or higher and 300° C. or lower.
