The present invention provides a fishing line guide that is attached to a fishing rod and guides the fishing line. The fishing line guide (100) includes a guide ring (110) through which the fishing line passes, a support leg (120L, 120R) connected to the guide ring at the upper end, and an attachment foot attached to the fishing rod (10) extending from the lower end of the support leg. (130). The attachment foot (130) has a proximal end (131B) adjacent to the lower end of the support leg (120L, 120R) and a distal end (131L) opposite to the proximal end. The mounting foot (130) includes a slit portion (132) and a pair of convex portions (135). The slit portion (132) is open to the attachment foot (130) along the central axis (CA2) of the attachment foot (130) from the base end (131B) toward the distal end (131L). The pair of convex portions (135) are located in the slit portion (132) and project toward the central axis (CA2).本発明は釣り竿に取り付けられて釣り糸を案内する釣り糸ガイドを提供する。釣り糸ガイド(100)は、釣り糸が通過するガイドリング(110)と、上端でガイドリングと連結される支脚(120L,120R)と、支脚の下端から延長して釣り竿(10)に取り付けられる取付足(130)とを含む。取付足(130)は支脚(120L,120R)の下端に隣接する基端(131B)と基端と対向する先端(131L)を有する。取付足(130)はスリット部(132)と一対の凸部(135)を備える。スリット部(132)は基端(131B)から先端(131L)に向かって取付足(130)の中心軸(CA2)に沿って取付足(130)に開いている。一対の凸部(135)はスリット部(132)に位置して中心軸(CA2)に向かってそれぞれ突出する。
