A fishing line is produced by forming a monofilament by subjecting a resin composition (C) containing 90 to 99.3% by weight of a polyamide resin (A) and 0.7 to 10% by weight of a silicone compound (B) having a number average molecular weight of 100,000 to 2,000,000 to melt-spinning and then drawing. This method can provide a fishing line which is excellent in abrasion resistance and also excellent in visibility. In this method, it is preferable to conduct melt-kneading of a part of the polyamide resin (A) with the silicone compound (B) in advance, adding of the residual polyamide resin (A) and further melt-kneading, subsequent melt-spinning, and drawing at a draw ratio of from 4 to 7.
