Abstract
The ball for ball games has a ball body and a spherical shell-shaped outer layer having a plurality of leather panels and disposed on the outside of the ball body. The plurality of leather panels each have a main body and an extending portion that is thinner than the main body and extends from a front-side portion of an outer end surface of the main body to configure an outer end surface of the leather panel. The extending portions of adjacent leather panels are bonded to each other with an adhesive and stitched together with a stitching thread. In the ball for ball games, the extending portion is provided with a reinforcing member for reinforcing an area thereof stitched with the stitching thread.
