An improved racket frame without the need of drilling holes comprises two compound material pipe bodies. A plurality of U-shaped embedded tubes are uniformly clamped between the two pipe bodies with two openings of each of the U-shaped embedded tubes facing the same direction. A compound material layer sheathes the two pipe bodies and the U-shaped embedded tubes with only the two openings of each of the U-shaped embedded tubes being exposed. The compound material layer is then placed into a mold and blown and heated to form an integral racket frame structure having th rough holes. Meshes conventionally exposed out of the racket frame are hidden in the racket frame, hence reducing abrasion of the meshes, lengthening the lifetime of use of the meshes, and enhancing the delicacy. Because there is no need of drilling holes twice, the structure of the racket frame will not be damaged.
