PROBLEM TO BE SOLVED: To provide an interline rod capable of keeping the strength of a fishing rod and favorably discharging water accumulated in the interior. SOLUTION: In this interline rod, a middle rod 3 is composed of a prepreg raw material in which a synthetic resin is impregnated in a reinforcing fiber and has a first layer 11 positioned on the innermost surface and orientating a reinforcing fiber in the circumferential direction, a second layer 12 laminated on the outside of the first layer 11 and orientating the reinforcing fiber in the axial direction, a third layer 13 laminated on the outside of the second layer 12 and orientating the reinforcing fiber in the circumferential direction and a forth layer 14 laminated in the outer periphery of a rod base side of the third layer 13 and orientating the reinforcing fiber in the axial direction. The thickness of the second layer 12 becomes thinner within a definite range from the end of the rod base side to which the forth layer 14 is laminated as the position of the layer 12 approaches the rod base side, and the forth layer 14 becomes thicker as the position of the layer 14 approaches the rod base side and the layer 14 forms an engaging male part 3a in which a definite range from the end of the rod base side is larger than other part. On the other hand, in the forth layer 14 forming the engaging male part 3a, a plurality of notches 15 are formed at intervals in the circumferential direction so that these depths do not attain the third layer 13.
