A plasma treatment method subjects a long object to be treated to plasma treatment by placing the long object to be treated in contact with plasma, the density distribution of which varies while selectively passing the long object to be treated through an area having high plasma density so that a surface of the long object can be thoroughly and uniformly subjected to plasma treatment. The method is applied to a plasma treatment apparatus, and a plasma-treated long object can be obtained by the method.

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.

A sheath-core composite conductive fiber having a sheath component made of a fiber-forming polymer containing conductive carbon black, is characterized in that, with respect to an inscribed circle of a core component and an inscribed circle of a sheath component in a cross section of the fiber, a radius (R) of the inscribed circle of the sheath component and a distance (r) between the centers of two inscribed circles satisfy a specific relationship, and a sheath-core composite conductive fiber having: a core component made of a polyester containing ethylene terephthalate as a main component, and a sheath component made of a mixture of a copolyester wherein ethylene terephthalate accounts for 10 to 90 mol % of constituent units thereof and carbon black. The conductive fiber can be used alone or in combination with other fibers in various applications, e.g., special working clothes such as dust-free clothes and interiors such as carpets.
