Abstract
Fishing rod stock is manufactured by winding three prepreg sheets around a mandrel to form three resin layers including high strength fibers. The first resin layer is formed over an entire axial length of the fishing rod stock. The second resin layer is formed on a rearward portion of the fishing rod stock. The third resin layer is smaller than the second resin layer and formed on a rearward region of the fishing rod stock. The high strength fiber of the second resin layer has a higher modulus of elasticity than the high strength fiber of the first resin layer. The high strength fiber of the third resin layer has a higher modulus of elasticity than the high strength fiber of the second resin layer. The high strength fibers of the second and third resin layers progressively increase in quantity toward a rear end of the fishing rod stock.
