1. A fishing line guide, comprising:

a guide ring through which a fishing line passes;

a support leg connected to the guide ring at an upper end of the support leg; and

an attachment foot extending from a lower end of the support leg and configured to be attached to a fishing rod, the attachment foot having a base end adjoining the lower end of the support leg and a leading end located opposite the base end,

wherein the attachment foot comprises:

a slit portion perforated in the attachment foot along a central axis of the attachment foot from the base end toward the leading end; and

a pair of convex portions located at the slit portion and protruding toward the central axis respectively,

wherein the pair of the convex portions extend from the base end of the attachment foot toward the leading end of the attachment foot, and

wherein each of the pair of the convex portions has a base end surface forming the base end of the attachment foot, a leading end surface located opposite the base end surface along the central axis, and an intermediate surface located between the base end surface and the leading end surface.

2. The fishing line guide of claim 1 , wherein at least a portion of each of the pair of the convex portions is located between the leading end and a line segment joining both outermost ends of a joint portion located between the attachment foot and a lower end of the support leg.

3. The fishing line guide of claim 1 , wherein the slit portion has a first slit located along the central axis of the attachment foot between the leading end and the pair of the convex portions, and

wherein a maximum width of the attachment foot is three times or more and four times or less of a distance between a first point at which a line passing a maximum width of the first slit and the line being perpendicular to the central axis meets an inner edge of the first slit and a second point at which the line meets an outer edge of the attachment foot.

4. The fishing line guide of claim 1 , wherein the slit portion has a first slit and a second slit which are located along the central axis of the attachment foot between the leading end and the base end, and

wherein the second slit has a second width less than a first width of the first slit.

5. The fishing line guide of claim 1 , wherein the slit portion extends from the base end up to the leading end and the attachment foot is divided by the slit portion.

6. The fishing line guide of claim 1 , wherein the pair of the convex portions are at least partially in contact with each other along the central axis of the attachment foot.

7. The fishing line guide of claim 1 , wherein the support leg comprises a pair of first support legs extending from the guide ring respectively, and a single, second support leg extending from the guide ring, the attachment foot extends from lower ends of the pair of the first support legs, further comprising:

another attachment foot extending from a lower end of the second support leg and configured to be attached to the fishing rod,

wherein said another attachment foot includes a pair of concave portions and the pair of the concave portions have a shape coinciding in shape with the pair of the convex portions.

8. The fishing rod including the fishing line guide of claim 1 .

9. A blank for a fishing line guide, comprising:

a ring portion;

a pair of first support leg portions extending from the ring portion; and

a first attachment foot portion extending from a first free end of each of the pair of the first support leg portions, the first attachment foot portion having a base end adjoining the first free end of each of the pair of the first support leg portions and a leading end located opposite the base end,

wherein the first attachment foot portion comprises:

a slit portion perforated in the first attachment foot portion along a central axis of the first attachment foot portion from the base end toward the leading end; and

a pair of convex portions located at the slit portion and protruding toward the central axis respectively,

wherein the pair of the convex portions extend from the base end of the first attachment foot portion toward the leading end of the first attachment foot portion, and

wherein each of the pair of the convex portions has a base end surface forming the base end of the first attachment foot portion, a leading end surface located opposite the base end surface along the central axis, and an intermediate surface located between the base end surface and the leading end surface.

10. The blank of claim 9 , further comprising:

a single, second support leg portion extending from the ring portion between the first support leg portions; and

a second attachment foot portion extending from a second free end of the second support leg portion,

wherein the second attachment foot portion has a shape coinciding in shape with the slit portion and the pair of the convex portions.

11. The blank of claim 9 , wherein the slit portion extends from the base end up to the leading end and the first attachment foot portion is divided by the slit portion.

12. A fishing line guide manufactured from the blank of claim 9 .
