  • Patent number: 11602139
    Abstract: A fishing rod includes a rod section and a fitting having a securing portion, the fitting being firmly secured to the rod section without inhibiting bending of the rod section, the securing portion having an excellent outer appearance. On a securing portion of a fishing line guide placed on the rod section, a prepreg sheet formed of plain-woven reinforcement fibers impregnated with a thermosetting resin is wound to secure the fishing line guide. The prepreg sheet is wound and secured so that, with respect to an axial direction, reinforcement fibers are in oblique directions, and intersecting angles of the reinforcement fibers in a winding region on a part of the rod section located beyond a distal end of the securing portion are smaller than those of the reinforcement fibers in a winding region on the securing portion.
