Abstract

PROBLEM TO BE SOLVED: To easily design the repulsive elasticity, vibration absorptivity, operability or the like according to a purpose by providing a racket frame main body made of FRP and a metal body provided in a part of the racket frame main body, and disposing the metal body in such a manner as to enclose the FRP part and be integrated with the FRP part. SOLUTION: A racket frame 1 comprising a face part 2, a shaft part 3 and a grip part 4 is formed by a racket frame main body 5 made of FRP and a metal body 7 provided on the shaft part 3. At this time, the metal body 7 is disposed in such a manner as to enclose the outer surface of the FRP layer 6 of the shaft part 3 and be integrated with the FRP layer 6. As metal for forming the metal body 7, preferably titanium or a titanium alloy which is light-weighted and excellent in rigidity and durability is used. Such a racket frame 1 can be easily manufactured by inserting FRP forming material in a metal mold where the metal body 7 is arranged and integrally forming the same. The metal body 7 may be provided on the face part 2.
