Therefore, the three-dimensional net rack 20 has enough structural strength and smaller weight, so that the racket is light in weight and can be operated and used lightly and agilely.

Preferably, an inner side surface of the frame wall 11 is radially recessed, and an outer peripheral surface of the three-dimensional net rack 20 is radially outwardly protruded, so that the three-dimensional net rack 20 can be more stably mounted on the frame wall 11 without being easily detached. However, the inner side of the frame wall 11 and the outer peripheral surface of the three-dimensional net frame 20 may be flat. The peripheral surface of the three-dimensional net frame 20 is preferably continuous and closed in a ring shape, so as to increase the connection area and connection strength with the inner side of the frame wall 11.

In this embodiment, the frame 10 is a fiber-reinforced member, the three-dimensional net frame 20 further includes two opposite side layers 22 and a skeleton 23 integrally connected between the two side layers 22, the two racket portions 30 are fiber-reinforced members and respectively covered on the two side layers 22, the fiber-reinforced members (such as glass fiber, carbon fiber or the like) have the characteristics of light weight and good structural strength, each side layer 22 can make the two racket portions 30 more flat after being covered, and the two side layers 22 are formed by, for example, prepreg fiber cloth laid on the two racket portions 30 and then hardened. The side layers 22 are provided with a plurality of openings 221, the framework 23 comprises a plurality of communication holes 231, the plurality of communication holes 231 correspond to and are communicated with the openings 221 of the side layers 22, and air resistance can be reduced when the racket 1 is patted.
