PROBLEM TO BE SOLVED: To provide a spool of lightweightness or inexpensiveness as possible as practicable while securing its own rigidity.SOLUTION: The spool incorporated in a reel and functioning to reel fishline is provided, being such that: both ends thereof in the shaft length direction have each a circular part 24 larger in outer diameter than the barrel body 22 between both the ends. The spool includes a spool body 25 made by integratedly molding at least one circular part 24 and the barrel body 22 of a fiber reinforcing resin wherein the spool body is such that at least the central part in the shaft length direction of the barrel body 22, in terms of the structure of the barrel body alone, has a high-strength parts P0 and t2 more resistant to crushing-to-flatness than those of any zones biased toward the any ends of the barrel body.COPYRIGHT: (C)2010,JPO&INPIT【課題】剛性を確保しつつ、可及的に軽量化を図るか或いは低コスト化を図ったスプールを提供する。【解決手段】リールに組み込まれて釣糸を巻回させるスプールであって、該スプールの軸長方向両端部は、該両端部の間領域の胴体部22に対して大きな外径の環状部24を有しており、少なくとも一方の環状部24と前記胴体部22とを繊維強化樹脂により一体に成形したスプール本体部25を具備しており、該スプール本体部は、少なくとも前記胴体部22の軸長方向中央部が、該胴体部だけの構造において、該胴体部の何れの端部寄り領域よりも潰れに対して高強度な高強度部P0’,t2を具備している。【選択図】図9
