To provide an electric wire coloring nozzle capable of spraying coloring material drops in every prescribed quantity on an intended position of an external surface of the electric wire.
The electric wire coloring nozzle 31 sprays liquid coloring material drops in every prescribed quantity on the surface of the electric wire and colors the electric wire. The electric wire coloring nozzle 31 has a cylinder-shaped first nozzle member 37 and a second nozzle member 50 coaxially jointed to each other inside of which, the coloring material flows along an arrow mark Q. The second nozzle member 50 is arranged nearer to the electric wire than the first nozzle member 37, and an inner diameter d of the second nozzle member 50 is smaller than an inner diameter D of the first nozzle member 37. An end face 50a of the second nozzle member 50 nearer to the first nozzle member 37 protrudes further toward inside of an inner face of the first nozzle member 37. The end face 50a is flat along a direction perpendicular to (crossing) the arrow mark Q.
