Leader for fly fishing of a vinylidene fluoride-based resin, with a butt, tapered and tippet sections

摘要

A vinylidene fluoride based resin having an inherent viscosity of 1.0 to 1.7 dl/g is used to provide a leader for fly-fishing, which has high knot strength and tensile strength, in which an unstable shape portion (constriction) having a smaller diameter than an average thread diameter of a tippet portion and melt fracture are not generated in a connection of a tapered portion with the tippet portion, and which is excellent in natural drift property.
