Abstract: A pass through fishing rod has a plurality of rod bodies, including a tip rod body having a first diameter and a plurality of larger-diameter rod bodies having successively increasing diameters greater than the first diameter. Each of the rod bodies has an inside surface defining a passage for a fishing line, a rear end section, and a front part having an inside diameter. The rod bodies are so formed that the rear end section of a rod body can be inserted and fastened to the inside surface of the front part Of a larger-diameter rod body. The fishing rod further includes line supporting means for supporting a fishing line which are installed in a portion of the inside surface of at least one rod body that is located further toward the rear end section of the rod body than the front part of the rod body.
