an intermediate section provided between the tippet section and the butt section, wherein the butt section is thicker than the tippet section, the intermediate section includes a front tapered portion having a thickness that gradually increases from the tippet section, a rear tapered portion having a thickness that gradually increases from the butt section, and a thicker portion than the butt section

wherein the front tapered portion includes a first front tapered portion having a thickness that gradually increases from the tippet section, and a second front tapered portion having a thickness that gradually increases from a rear end of the first front tapered portion with respect to a length direction at a larger rate as compared to increase in the thickness of the first front tapered portion.

2. A leader for fly fishing formed of a single monofilament line, the leader comprising:

a tippet section to which a fly is tied;

a butt section to which a fly line is tied; and

an intermediate section provided between the tippet section and the butt section, wherein the butt section is thicker than the tippet section, the intermediate section includes a front tapered portion having a thickness that gradually increases from the tippet section, a rear tapered portion having a thickness that gradually increases from the butt section, and a thicker portion than the butt section wherein the front tapered portion includes a first front tapered portion having a thickness that gradually increases from the tippet section, and a second front tapered portion having a thickness that gradually increases from a rear end of the first front tapered portion with respect to a length direction at a smaller rate as compared to increase in the thickness of the first front tapered portion.

3. A leader for fly fishing formed of a single monofilament line, the leader comprising:

a tippet section to which a fly is tied;

5. A leader for fly fishing formed of a single monofilament line, the leader comprising:

a tippet section to which a fly is tied;

a butt section to which a fly line is tied; and

an intermediate section provided between the tippet section and the butt section, wherein the butt section is thicker than the tippet section, the intermediate section includes a front tapered portion having a thickness that gradually increases from the tippet section, a rear tapered portion having a thickness that gradually increases from the butt section, and a thicker portion than the butt section wherein the intermediate section includes a non-tapered portion having a constant thickness between the front tapered portion and the rear tapered portion.
