PROBLEM TO BE SOLVED: To provide a leather-like sheet which exhibits a sufficient surface abrasion resistance and an excellent non-slip properties because of its high sweat-absorbing ability under wet conditions. SOLUTION: The leather-like sheet for ball comprises a fiber-entangled fabric and a porous surface layer with unevenness pattern disposed on the surface of the fiber-entangled fabric. Microholes having an average diameter of 5 to 100μm are formed on surfaces of the outwardly projecting pebbles on the porous surface, but the microholes are substantially not formed on the surfaces of the valleys.
