A skin material for balls which is a sheet-form material comprising a base layer and formed on one side there of a coating layer made of a polymeric elastomer, characterized in that (1) the coating layer is composed of three layers (C-1), (C-2), and (C-3) disposed in this order from the surface side, (2) the layer (C-3) on the base layer side is made of a porous polymeric elastomer, (3) the layer (C-1) on the surface side is made of a polymeric elastomer containing a pressure-sensitive adhesive, and (4) the coating layer comprises one or more polymeric elastomers which have or do not have fine through-holes extending from the surface side to the base layer; and a ball having the skin material bonded to the surface. The skin material for ball-game balls brings about excellent wet gripping and is excellent also in wearing resistance and impact absorption.
