Abstract
A sporting rod member which is strong against flexure, which is improved in tough and balance when it is flexed, and which can be made finer in thickness and lighter in weight. The sporting rod member uses a solid rod (8). The solid rod (8) is made up of a solid-state core member (10) and an outer layer (12) formed of fiber reinforced resin and disposed on the outside of the core member (10). In the solid rod (8), most of reinforcing fibers that are used in at least one of the solid-state core member and outer layer and that extend substantially in the axial direction thereof have a longitudinal elastic modulus of 40 ton/mm2 or higher.
