A surface material for balls, formed of a sheet-shaped material having a coating layer formed from an elastic polymer on one surface of a base material layer, (1) said coating layer being formed of three layers C- 1, C- 2 and C- 3 which are arranged in the order of C- 1, C- 2 and C- 3 from a front surface side, (2) the layer C- 3 being present on the base material layer side and formed from a porous elastic polymer, (3) the layer C- 1 being present on the front surface side and being formed from an elastic polymer containing a tackifier, and (4) the coating layer being formed from the elastic polymers having fine through holes reaching the base material layer from the front surface side or having no such fine through holes, and a ball having a surface to which the above surface material is bonded. The present invention provides a surface material for balls for ball games, which is excellent in gripping characteristic at a moistened time and is also excellent in abrasion resistance and impact absorption capability.
