PROBLEM TO BE SOLVED: To provide a device for manufacturing an optical fiber tape core, capable of setting a width dimension or the like of a connecting portion for mutually connecting optical fibers to a desired dimension while integrating a plurality of optical fibers. SOLUTION: The device includes: a coating die section 10 configured to align a plurality of optical fiber element wires 8 at intervals and to feed them while supplying uncured resin each between the plurality of optical fibers 8; an ultraviolet irradiation unit 30 configured to irradiate the plurality of optical fiber element wires 8 fed from the coating die section 10 with ultraviolet energy to form a connecting portion 9a by cured resin each between the optical fiber element wires 8, in which the irradiation position in an optical fiber feeding direction A can be varied; a tape width measurement section 40 which measures the width of the connecting portion 9a cured in the ultraviolet irradiation section 30; and a control unit 60 which calculates a width of the connecting portion 9a from the measurement result in the tape width measurement unit 40 and adjusts the irradiation position of the irradiation unit 30 based on the measured width of the connecting portion 9a.
