The present invention discloses a composite fishing line (1) manufactured by braiding eight bundles of fibers selected from two different types of fibers, one being a high molecular-weight polyethylene fiber (2) and the other being a high molecular-weight expanded polytetrafluoroethylene (ePTFE) fiber (3), such that the composite fishing line has the properties of both high molecular-weight polytetrafluoroethylene (PTFE) fibers and polyamide fibers to improve the strength, wear-resistance, cross-sectional roundness, and water resistance of the high-performance fishing line and achieve the effect of reducing the diameter of the fishing line.
