OPTICAL FIBER STRUCTURE, ILLUMINATION DEVICE, ENDOSCOPE, AND OPTICAL FIBER STRUCTURE MANUFACTURING METHOD

摘要

An optical fiber structure of the present application is formed by arranging, inside a tubular resin body, a plurality of optical fiber bare wires in a circumferential direction, the optical fiber bare wires extending along the longitudinal direction of the resin body, and has a linear cut at an intermediate position in the longitudinal direction of the resin body, the linear cut reaching the inner cavity from the outer circumferential surface of the resin body and extending substantially in parallel with the bare wires.
