Abstract
An optical fiber unit includes: an optical fiber bundle formed by bundling a plurality of optical fibers; and a plurality of bundling members. One bundling member of the plurality of bundling members is wound on an outer circumference of the optical fiber bundle in a length direction of the optical fiber bundle, while reversing a winding direction alternately, and is joined to another bundling member at a section where the winding direction is reversed. A ratio of a width of a cross-section of the bundling member to a thickness of the cross-section of the bundling member is smaller than 20.
