れない。However, a high-temperature curing type thermosetting resin is suitable for obtaining a rod tube exhibiting high rigidity, high strength and specific strength. The difference between the winding temperature (normal temperature) and the molding temperature is large. For this reason, in a fiber reinforced prepreg using a high-temperature curing type thermosetting resin, the obtained rod pipe may bend due to the influence of the coefficient of thermal expansion of the reinforcing fibers and the like. This phenomenon is remarkable in a rod tube having a relatively small outer diameter, for example, a tip rod tube. If the rod tube is bent as described above, the bent will adversely affect the directionality of the fishing rod, and the deflection will increase, and a good tone cannot be obtained.
