An optical fiber structure according to the present application includes a cylindrical resin body, and a plurality of circumferential arrays of optical fiber bare wires disposed within the resin body and extending along a longitudinal direction of the resin body. The resin body includes a linear slit provided at a location intermediate the length of the resin body. The linear slit extends from an outer surface to an inner bore of the resin body and extending substantially parallel to the bare wires.
