Abstract: An optical fiber ribbon manufacturing device comprising: a tape die 20 for coating a plurality of single-core coated optical fibers 2 with a photocurable resin; a split die 30 for forming a split portion in the photocurable resin present between the single-core coated optical fibers; and a light irradiation device 40 for irradiating the photocurable resin with light to cure the photocurable resin, wherein both the tape die 20 and the split die 30 are temperature-controlled or only the split die 30 is temperature-controlled, a temperature of the tape die 20 is higher than a temperature of the split die 20, and the temperature of the split die 20 is lower than the temperature of the tape die 30.
