To impart a sure shark evasion function during surfing to an existing surfboard by post-installment.SOLUTION: A fin 110 for a surfboard includes: a fin body 111 to be attached on a bottom surface 101b side of a surfboard 101; and a magnetic member 113 attached to the fin body 111 containing ferromagnetic body. It is preferable that the magnetic member 113 is provided in an area on a base end side of the fin body 111. Attaching the magnetic member 113 to the fin body 111 causes the magnetic member 113 having a shark evasion function to be immersed underwater during surfing, so that the shark evasion function can be further assured.SELECTED DRAWING: Figure 1

    【課題】既存のサーフボードに対して、後付けでサーフィン中における確実なサメ除け機能を付与する。【解決手段】サーフボード用フィン110は、サーフボード101のボトム面101b側に取り付けられるフィン本体111と、フィン本体111に設けられ、強磁性体を含む磁性部材113と、を備える。磁性部材113は、フィン本体111の基端側の領域に設けられていることが好ましい。磁性部材113をフィン本体111に設けることによって、サーフィン中にサメ除け機能を有する磁性部材113が海面下に浸かった状態となるので、より確実にサメ除け機能を発揮することができる。【選択図】図1
