PROBLEM TO BE SOLVED: To provide a ball which can be easily gripped.SOLUTION: A ball is formed by: bonding plural pieces of cuticle bodies 3 formed of a material which hardly slips, such as a soft resin, a rubber, and a foam thereof, to a sphere 2 with an adhesive agent 6 to cover the whole body of the sphere 2, and rear side recessed parts 5 serve as hollow parts 7 surrounded by the cuticle body 3 and the sphere 2. When a user grips the ball 1, adjustment between ease of being dented on surface parts of the cuticle bodies 3 and repulsion can be achieved, so that the user can easily grip the ball 1, pitch the ball and catch the ball. By volumes of the hollow parts, softness can be slightly adjusted, and softness quality is enhanced by using force of an air spring, so that when gripping the ball 1, the user can grip the ball 1 softly. A trough part based on a chamfer part 4 is formed on a boundary between the adjacent cuticle bodies 3, so that the user can easily grip the ball 1 by touching the trough parts. The cuticle body 3 may be formed of a cushion part having elasticity on the sphere 2 side and a cuticle part for covering a surface part side of the cushion part.SELECTED DRAWING: Figure 2 【課題】掴みやすいボールの提供。【解決手段】軟質樹脂、ゴム、及びそれらの発泡体等の滑りにくい材料からなる複数個の表皮体３が球体２に接着剤６で接着されて球体２を全体的に被覆し、裏側凹部５が表皮体３と球体２とで囲まれた空洞部７になり、人がボール１を掴んだ時、表皮体３の表面部の凹みやすさと反発力との調整が取れ、ボール１が掴みやすく投げやすくキャッチしやすい構造になっている。空洞部の容積により、軟らかさを微調整できると共に、空気ばねの力を利用して軟らかさの質を高め、人がボール１を掴む時、ボール１をソフトに掴むことができる。隣接する表皮体３どうしの境目に面取り部４に基づく谷部が形成され、谷部に手がかかり、ボール１が握りやすくなる。表皮体３を球体２の側の弾性を有するクッション部とクッション部の表面部の側を覆う表皮部とから構成してもよい。【選択図】図２
