Abstract
A method for manufacturing an optical fiber includes applying a first resin composition, forming a primary resin layer, applying a second resin composition, and forming a secondary resin layer. An ultraviolet LED used a light source in the forming the primary resin layer and the forming the secondary resin layer. In the forming the primary resin layer, an effective power consumption represented by formula (1) is 0.056 kWs or more and 0.230 kWs or less, where N is a number of light sources, Bn [kW] is a rated power of an n-th light source, φn is a predetermined rate of power of the n-th light source, and tn [s] is an irradiation time of the n-th light source.
