Abstract: Where a super-elastic alloy is used as a core material, boundary separation can be prevented on substantial deflection. The super-elastic alloy is used as the core material, an outside layer made with fiber-reinforced resin is provided outside except the tip part region of the core material, and a resin-rich layer greater in resin ratio than the outside layer is provided between the outside layer and the core material so as to be adjacent to the core material.

Abstract: A tubular member is disclosed which achieves reduced weight, prevention of unevenness or chips in decoration, and good decoration quality. This tubular member is formed as follows a fiber reinforced prepreg in which reinforcing fibers are impregnated with a synthetic resin is wound to form a main body of the tubular member, and decorative particles are embedded into an outer surface side resin of the fiber reinforced prepreg disposed on an outermost side of the main body. An average thickness of the outer surface side resin layer of the fiber reinforced prepreg on the outermost side is formed to be smaller than an average diameter of the reinforcing fibers of this fiber reinforced prepreg on the outermost side, and an average thickness of decorative particles is formed to be equal to or less than the average thickness of the outer surface side resin layer.
