The invention discloses a sport ball and a sport ball manufacturing method. The sport ball comprises four layers of a rubber liner, a wrapping yarn layer, a gluing layer and a leather layer, wherein the wrapping yarn layer is arranged on the surface of the rubber liner, the exterior of the wrapping yarn layer is covered by the gluing layer, the raw material of the gluing layer is raw rubber sheets, and the gluing layer is vulcanized and glued to the outer leather layer for integration. According to the invention, the sport ball is divided into four layers, the wrapping yarn layer is arranged on the rubber liner, the exterior of the wrapping yarn layer is covered by the gluing layer, the gluing layer is vulcanized and glued to the outer leather layer, and the leather layer is composed of aplurality of leather sheets forming the surface of the sport ball. The gluing layer and the leather sheets are subjected to low-temperature rapid vulcanization treatment to be integrated into a whole,no glue adhesive is used, thus the environment friendliness and firmness of the product are improved to a greatest extent on the aspects of production and use; and no sewing line is used, and productmanufacturing is automatically finished through a mold, thus labor costs are saved and working efficiency is improved.
