    摘要: Provided are: a sheet-like ball material including a fibrous base material, and an elastic polymer cover layer that is laminated on a surface of the fibrous base material, in which continuous pebbles and discontinuous valleys are formed on a surface of the cover layer, the valleys discontinuously formed are formed at average intervals of 0.5 to 3 mm, the valley has a depth of 50 to 500 μm, a vertical projected area of each valley is 1 to 5 mm2, and a total area of the vertical projected area of each valley accounts for 3 to 30% relative to a surface area of the elastic polymer cover layer; a ball used for volleyball or beach volleyball including the sheet-like ball material, which is excellent in the controllability for all types of ball plays such as tossing and serving in the smoothness of the attenuation degree in the ball speed of the ball during flight of the ball, and in the design, e.g., three-dimensional shape, which is not realized in a heretofore-existing ball, and also has a sufficient surface abrasion resistance; and a sheet-like ball material suitably used for such balls.
