A badminton racket is composed of an oval frame, a grip, and a shaft fastened between the oval frame and the grip. The shaft has a shell which is formed of a plurality of fiber-reinforced plastic layers and at least one metal gauze layer. The metal gauze layer is formed of a first metal filament and a second metal filament such that the first metal filament is extended in a direction forming an angle with the longitudinal axis of the shaft, and that the second metal filament is extended in a direction forming an angle with the longitudinal axis of the shaft. The angles so formed are preferably 60 degrees each.
