Abstract
A method for producing an optical fiber unit by winding at least two bundling members on the outer circumference of an optical fiber bundle formed by bundling a plurality of optical fibers, including: feeding the optical fiber bundle from a fiber passage member; feeding the bundling members while forming intersection points between two of the bundling members on the outer circumference of the optical fiber bundle by feeding at least one of the bundling members from a bundling member passage part of a rotating member arranged to the outer circumference of the fiber passage member, while causing the rotating member to oscillate, with the feeding direction serving as the axis; and fusion-bonding the bundling members at their intersection points.
