PROBLEM TO BE SOLVED: To provide a fishing line made of a PVdF monofilament, having a high visibility and excellent strength characteristics at the same time, and capable of being more easily and inexpensively manufactured than conventional technologies.SOLUTION: The fishing line is made of the monofilament obtained by fusing and spinning polyvinylidene fluoride resin, and has such strength characteristics that the tensile strength is 600-760 MPa and that the knot strength is 475-550 MPa. The surface roughness of the monofilament is in the range from 2.5 &mum to 7.5 &mum, and the total light transmittance measured by a turbidimeter is 90% or less.COPYRIGHT: (C)2012,JPO&INPIT【課題】高い視認性と優れた強力特性と同時に兼ね備え、さらには従来技術に比べて容易でかつ安価に製造することができるPVdFモノフィラメントからなる釣糸の提供。【解決手段】ポリフッ化ビニリデン系樹脂を溶融紡糸して得られるモノフィラメントからなり、引張強度が600~760MPa、結節強度が475~550MPaの強度特性を有すると共に、モノフィラメントの表面粗度が2.5μm~7.5μmの範囲にあり、かつ濁度計で測定した全光線透過率が90%以下であることを特徴とする釣糸。【選択図】なし
