The present invention relates to a float for fishing which minimizes the movement of a fishing gut simultaneously with maintaining the natural state of the fishing gut without bending as a through-hole of which the cross-sectional area becomes narrower from the top to the bottom inside a buoyant body and the upper part is formed into a straight slit shape and the lower part is formed into a globe shape makes the fishing gut smoothly move inside the through-hole by minimizing the friction between the through-hole and the fishing gut as the top surface of the floating body is protruding to be convex upward for maintaining the shape of a curved line of the through-hole of the straight slit shape has no need to mount a bead fishing tackle as a locking protrusion is formed for preventing a cotton thread of the fishing gut from randomly passing the lower part of the through-hole easily fishes fish sensitive species such as opaleye by forming a point of action of buoyancy with respect to the float to make fish, which goes downward in the water while taking the bait, feel no remaining buoyancy as the cotton thread knot is hung on the lower part of the float and re-puts the cotton thread knot in a reverse direction by pulling the fishing gut in the opposite direction as the inner diameter of the through-hole is re-extended from a spot even though the cotton thread knot of the fishing gut forcibly passes through the through-hole. A float for fishing according to one desirable embodiment of the present invention is characterized by including a floating body and a through-hole which penetrates through the inside of the floating body in the longitudinal direction and of which the upper part is formed into a straight slit shape and the lower part is formed into a globe shape to make the cross-sectional area thereof becomes narrower from the top to the bottom inside the buoyant body.COPYRIGHT KIPO 2014본 발명은 부력재 본체의 내부에 상부에서 하부로 갈수록 그 단면적이 점차적으로 좁아지는 관통구가 형성되되 상부는 일자형 슬릿 형상으로 형성되고
