The present invention provides a fishing line comprising a composite yarn having a core-sheath structure, where the composite yarn comprises a core part having a core yarn containing a short fiber and a sheath part having a sheath yarn containing a long fiber the long fiber in the sheath part and the short fiber in the core part are intertangled with each other and the core yarn and the sheath yarn are integrated with use of an adhesive resin. The fishing line of the present invention has a robust core-sheath structure which prevents nude yarn or nep from being developed, excellent operability, adjustable specific gravity, excellent tensile strength, high weatherability and water resistance, low water content, low elongation rate, and low probability of unravelling constituent fibers at a cut site.
