摘要： An objective of the disclosure is to improve workability in extracting optical fibers in an optical fiber unit in which a bundle of optical fibers is bundled by bundling members, and to suppress/prevent an increase in transmission loss even when tension is applied to the bundling members. This optical fiber unit includes: a plurality of optical fibers; and at least three bundling members that bundle the optical fibers into a bundle. A first bundling member, among the plurality of bundling members, is arranged along a length direction of the bundle of optical fibers so as to be wound on an outer circumference of the bundle of optical fibers. The first bundling member is joined with a second bundling member at a contact point where the first bundling member contacts the second bundling member, and is joined with a third bundling member, which is different from the second bundling member, at a contact point where the first bundling member contacts the third bundling member. The first bundling member's winding direction with respect to the bundle of optical fibers is reversed at the contact point with the second bundling member and at the contact point with the third bundling member.
