PROBLEM TO BE SOLVED: To provide a wire-shaped body in which a prescribed position is specified without being erased even by cleaning and without requiring measurement and in which, at the prescribed position, a tool is dispensed with in removing a jacket, and also to provide the manufacturing method of the wire-shaped body. SOLUTION: A pigmented coated glass optical fiber 11 obtained by applying ultraviolet ray setting resin and pigmentation on a glass optical fiber is covered with a jacket 13, on which groups of a plurality of recesses 15 are formed on the circumferential surface and in the axial direction with prescribed spaces k apart. It is desirable that the group of recesses 15 is functionally shaped so that the jacket 13 is parted by imparting external tensile force to the recesses in the axial direction.
