A yarn object which, even though made of ultra-high-molecular-weight polyethylene, can be satisfactorily prevented from color fading caused by contact with other objects or the like, can be produced easily at low cast, and can maintain high strength. The yarn object is colored with a colorant. The yarn object includes a core yarn 2 colored with a predetermined colorant and an outer-layer yarn 3 disposed on the periphery of the core yarn. The outer-layer yarn 3 is disposed in such a manner that the core yarn 2 is prevented from contacting with other objects. The outer-layer yarn 3 includes a transparent filament and a space 4 is formed between the outer-layer yarns 3. The color applied to the core yarn 2 is externally visible through the transparent outer-layer yarn 3 and the space therebetween 4.
