To provide an interline float reacting, by changing a float angle by smaller force, to difference of wide-angle familiarity, or to wide-angle pulling by fish, of a tackle under the float which has been difficult to understand hitherto by an angler.SOLUTION: In an interline float, a buoyancy part 11 having a lighter specific gravity than a float body is provided with a size of 1/70 or more and 1/7 or less of an outside volume of the interline float, and a gravity center of only the buoyancy part having a lighter specific gravity than the float body is provided on a position within 30% of a distance between both ends of a fishing line-introducing hole 16, from either position of both ends of the fishing line-introducing hole 16 of the interline float.SELECTED DRAWING: Figure 3【課題】釣人が今まで解りにくかったウキより下の仕掛け、の広角な馴染み方の違いや、魚の広角な引き込みなどに、より小さな力でウキが角度を変えることで反応する中通しウキを提供する。【解決手段】中通しウキにおいて、ウキ本体よりも比重の軽い浮力部１１が中通しウキの外形体積の７０分の１以上７分の１以下の大きさで設けられ、前記中通しウキの釣糸通し孔１６の両端いずれかの位置から、前記釣糸通し孔１６の両端の距離の３０%以内の位置にウキ本体よりも比重の軽い浮力部のみの重心が設けられている。【選択図】図３
