To make it difficult for sponge sheets to stick to each other even when multiple sponge sheets are stored with overlapping, and to improve workability when taking the desired number of sponge sheets from the top.SOLUTION: The sponge sheet 1, which is made of extruded rubber or thermoplastic elastomer, has a plurality of ribs 10 protruding from one side 1a in the thickness direction and extending in a predetermined direction at a predetermined pitch. When the height of rib 10 is h, the pitch of rib 10 is x, and the radius of the arc face constituting the outer surface of rib 10 is R, the height of rib 10, the pitch of rib 10, and the radius of the arc surface constituting the outer surface of rib 10 are set so that the relationship 12.595+(-9.5×h)+(-38.1×R)+(16.7×x)>0 is satisfied.SELECTED DRAWING: Figure 3
【課題】複数のスポンジシートを重ねて保管してもスポンジシート同士を貼りつき難くし、所望枚数のスポンジシートを上から取る際の作業性を向上させる。【解決手段】ゴム又は熱可塑性エラストマーを押出成形してなるスポンジシート1には、厚み方向一方の面1aから突出して所定方向に延びるリブ10が所定ピッチで複数本形成されている。リブ10の高さをhとし、リブ10のピッチをxとし、リブ10の外面を構成する円弧面の半径をRとした時、12.595+(-9.5×h)+(-38.1×R)+(16.7×x)>0の関係を満たすように、リブ10の高さ、リブ10のピッチ、リブ10の外面を構成する円弧面の半径が設定されている。【選択図】図3
