Abstract
Surface panels of a sports ball are arranged to facilitate bending of their outer peripheral edge portions into an arc, without reducing strength of an elastic member, to define a groove at a seam between adjacent panels. Panels are adhered through the elastic members to a body defining a ball core with high adhesion strength. The panels have sheet material backed by an elastic member, each panel having an arched portion formed by bending inwardly an outer peripheral edge portion of each panel with a radius of curvature more than the thickness of the panel, after formation of many apertures in an inner peripheral edge portion of the elastic member. Lower edges of the arched portions of adjacent panels abut each other. A groove is defined at seams between adjacent panels, and the panels are adhered to a ball core body by adhering the elastic members to the body.
