[Problem] To make a ball easy to be grabbed. [Solution] In a skin bodywhich covers a ball main body, a skin partand a circumferential wall partprotruding from a peripheral edge part of the skin partto a back side are integrally formed by molding of injecting a soft material made of resin or rubber into a mold. Alternatively, a structure is such that a step part or flat surface part where a finger is hung is provided on a front surface of the ball main bodyor a front surface of the skin bodywhich covers the ball main body. Alternatively, a front surface of one of adjacent skin bodiesand a front surface of the other thereof configure a step part in a radial direction of a ball. With this, even in a ball game where the ballis grabbed with hand such as a handball game, when a person grabs the ball, the skin partof the skin bodyis easily recessed, a finger is hung on the step part, or the flat surface part is touched with a finger to make the person feel that the ballhas a small outer diameter. With this, the ballbecomes easy to be grabbed, thereby making it easy to throw or catch the ball
