To provide a racket frame of light weight excellent in impact resilient performance, having satisfactory operability, and having enough strength.
In this racket frame made of a fiber-reinforced resin and/or thermoplastic resin for constituting continuously a head part surrounding a hitting face, a throat part, a shaft part and a grip part, fiber-reinforced prepregs 19a in which a carbon fiber having a tensile elastic modulus of 200 GPa-600 GPa is used as a reinforcing fiber, and in which a fiber angle of the reinforcement fiber is 0°±30° with respect to the axial direction of the racket frame are layered collectively along the hitting face direction in the cross section of the racket frame, and a ratio A/B of a hitting-directional thickness A in the cross section of the racket frame to an in-plane-directional thickness B thereof is made to be brought within a range of 1.2-3.0.
