A sportsball includes a ball carcass, an inflatable ball body received in a ball cavity of the ball carcass, and a stitchless seam arrangement which includes an elongated adhesive layer having a contour matching with a contour of an opening of the ball carcass, wherein after the ball body is disposed in the ball carcass, edge portions of the opening are adhered on an outer surface of the ball body via the adhesive layer, such that the opening is sealed to close the ball cavity for enclosing the ball body in the ball cavity of the ball carcass in a stitchless seam manner. Therefore, the manufacturing method of the sportsball excludes the traditional final assembling operation of hand stitching to reduce the time-consuming manufacturing procedure of the sportsball while being cost effective.
