Abstract
Abstract A fishing rod comprising a plurality of fiber reinforced synthetic resin laminations and a specific space retaining layer provided intermediate the outermost layer and the innermost layer thereof. Due to the provision of this space retaining layer, a distortion due to a bending moment is effectively reduced and the fishing rod can enjoy light weight and high stiffness.
