PROBLEM TO BE SOLVED: To impart a soft cushion property and water a absorption-resistant property to the surface of an outer layer of a leather which is used for a soccer ball and so forth by providing a nonporous high molecular elastic body layer, a porous high molecular elastic body layer, a layer which is composed of a high molecular elastic body and a nonwoven fabric, and a layer which is composed of a nonwoven fabric as the first to fourth layers. SOLUTION: When a leather pattern sheet which is suitably used for an outer layer of a succor ball is formed, nonporous high molecular elastic body layer is used as the first layer, a porous high molecular elastic body layer is used as the second layer, and the third layer composed of the high molecular elastic body which constitutes the second layer and a nonwoven fabric, and the fourth layer composed of the nonwoven fabric which is continued from that of the third layer are used. A ball is composed by glueing the leather pattern sheet with the fabric in a state of infiltrating an adhesive from a side of the nonwoven fabric, i.e., the fourth layer which does not touch with the third layer to 1/4 to 3/4 of the thickness of the fourth layer. Preferably, water repellancy is imparted to the nonwoven fabric by using water repellent to enhance its water absorption-resistant properties.
