PROBLEM TO BE SOLVED: To provide a fishline capable of decreasing a load applied to a luring material, capable of being enhanced in strengths and reduced in elongation by decreasing water stream friction and increasing a diameter of the fishline, and capable of enhancing transmission of a strike by a fish. SOLUTION: This fishline is used as a supporting fishline 3, 3a joined to a pulling fishline 2 and has a resistance removing means with which a stream of water contacting with a surface of the supporting fishline 3 is led to a rear side of the supporting fishline 3 along a stream line 12. The resistance removing means functions so that the surface of the supporting fishline 3 is formed into a shape having a plurality of concavities 5, and therefore, a Karman's vortex train 11 is formed. Negative pressure 10 developed on a rear surface of the supporting fishline 3a is relieved by making the supporting fishline 3a hollow positioning, an upper end of the fishline 3a above a surface of the water, sealing a lower end thereof with the luring material 4, forming a plurality of pervious holes 7 on a surface thereof, and by ejecting positive atmospheric pressure a to become a negative pressure.
