The present invention relates to a fishing line comprising a composite yarn having a core-sheath structure, the composite yarn includes a core composed of a core yarn containing a short fiber, a sheath composed of a sheath yarn comprising a long fiber It consists of short fibers of the long fibers and the core portion of the sheath portion is entangled, further core yarn and sheath yarn me to provide a fishing line which are integrated with an adhesive resin. Fishing line of the present invention, core-sheath structure, without development of robust, nude yarn or nep, excellent operability, it is possible weighting, further, the tensile and excellent strength, a high weather resistance and water resistance, water The rate is low and elongation is low, there is no unraveling of the constituent fibers in the cutting section.本発明は、芯鞘構造の複合糸からなる釣糸であって、複合糸は、短繊維を含有する芯糸で構成される芯部と、長繊維を含有する鞘糸で構成される鞘部とからなり、鞘部の長繊維と芯部の短繊維が交絡しており、さらに芯糸および鞘糸が接着性樹脂で一体化されている釣糸を提供する。本発明の釣糸は、芯鞘構造が堅固でヌードヤーンやネップの発生がなく、操作性に優れ、比重調整可能であり、さらに、引っ張り強度に優れ、高い耐候性および耐水性を有し、含水率が低く、伸度が低く、切断部における構成繊維のばらけがない。
