To provide a bundling device capable of efficiently and effectively obtaining a sufficient cohesion force by a binding yarn without inviting weight saving and without deteriorating its appearance, maintaining a desired bundled form, and having a slippery surface Provided is a fish hook and a fishing hook binding method which facilitate the winding work of a binding yarn even when a fishing hook is used.SOLUTION: The fishhook 4 of the present invention comprises a plurality of constituent fishhooks 4A, 4B, 4C arranged in an anchor shape with the shaft portion 4a along, and a bundle yarn 12 is wound around the shaft portion 4a of the constituent hooks And a binding portion 10 formed by winding. The binding portion 10 includes a first sparsely wound layer 10 A formed by spirally winding the binding yarn 12 around the shaft portion 4 a from one end side 30 toward the other end side 31, and a first sparsely wound layer 10 A second sparse winding layer 10B formed by winding a spiral wound spirally while filling a gap from the other end side to the one end side so as to overlap with the uncoiling wound layer 19A of 1, And a close wound winding layer 10C formed on the sparsely wound layer 10B by densely winding around the first and second sparsely wound layers.(FIG.【課題】重量化を招くことなく、また、外観を損ねることなく、結束糸による十分な結束力を効率的且つ効果的に得ることができ、所望の結束形態を維持できるとともに、表面が滑りやすい釣針を用いる場合でも結束糸の巻回作業がし易い釣針及び釣針結束方法を提供する。【解決手段】本発明の釣針4は、軸部4aを沿わせた状態で錨状に配置される複数の構成釣針4A,4B,4Cと、構成釣針の軸部4aの周囲に結束糸12を巻き付けて成る結束部10とを備える。結束部10は、結束糸12を軸部4aの周囲に一端側30から他端側31へ向けて螺旋状に巻き付けて形成される第1の疎巻き巻回層10Aと、結束糸12を第1の疎巻き巻回層19A上に重ねて他端側から一端側へ向けて隙間を埋めつつ螺旋状に巻き付けて形成される第2の疎巻き巻回層10Bと、結束糸を第2の疎巻き巻回層10B上に第1及び第2の疎巻き巻回層よりも密に巻き付けて形成される密巻き巻回層10Cとを有する。【選択図】 図5
