  • Patent number: 9010014
    Abstract: A rod body for a fishing rod, in which torsional rigidity and the like are enhanced by exercising ingenuity in direction of arrangement of a prepreg tape, is provided. An inner layer 23 is formed by winding a main pattern, which is constituted by a prepreg sheet 52 having a length corresponding to the length of a rod body and provided with reinforcing fibers 42 uniformly aligned, so that reinforcing fibers 42 are tilted relative to the rod axis. An outer layer 25 is formed by helically winding a prepreg tape with small-width 70, which is constituted by reinforcing fibers 42 uniformly aligned in the longitudinal direction, in the rod axis direction so that ends of the prepreg tape 70 in the small-width direction thereof abut closely against each other. The reinforcing fibers 42 of the prepreg sheet 52 and the reinforcing fibers 42 of the prepreg tape 70 are wound so as to cross each other when viewed in a radial direction, with the winding being made helically in directions opposite to each other.
