- the thickness of the porous body 3 is preferably 0.05 mm or more and 1.4 mm or less.
- the bending elastic modulus of the porous body 3 differs depending on the manufacturing method and the like, and this causes the degree of deformation at the time of suction to be different.

- A is equal to the diameter of the through hole 21. This is because if B / A 2 is less than 0.015, depending on the material and structure of the porous body 3, the porous body 3 may be greatly deformed by suction.
- More preferable B / A 2 is 0.025 or more under the condition that the thickness of the porous body 3 is in the range of 0.05 to 1.4 mm, and most preferably 0.025 to 0.040. .

- the suction amount was set to 10 L / min, and a series of cycles of adsorption, conveyance, and desorption of the aluminum foil was performed 100 times between two tables, and the number of times of poor adsorption was counted.
- the surface of the aluminum foil after a test was observed and it was confirmed visually whether the adsorption trace remained.
- Table 1 shows the specifications, B / A 2 and test results for each adsorption sheet.

Abstract
Description
超高分子量ポリエチレン粉末(分子量500万、嵩密度0.47g/cm3、平均粒子径120μm)を内径500mm、高さ500mmの金型に充填し、これを金属製耐圧容器に入れ、容器内を10hPaまで減圧した。その後、容器内に加熱された水蒸気を導入することにより、容器内を160℃、6080hPaとして5時間の加熱を行い、ついで徐冷を行って、円筒状の焼結ブロックを得た。この焼結ブロックを旋盤により種々の厚さにカットして焼結シート体を切り出し、これを100mm各にカットした。この焼結シート体をプレス機により130℃、30Paで1時間プレスして、0.025~1.0mmの厚さの多孔質体を作製した。
焼結ブロックから切り出す焼結シート体の厚さを厚くした以外は実施例と同様にして、1.5mmの多孔質体を作製した。これを、実施例と同様に、直径6.0mmの貫通孔が設けられた基板(ポリエチレン板)に貼着して、吸着用シートを得た。なお、多孔質体については、実施例と同様にして気孔率を算出した。
実施例1~8および比較例の吸着用シートについて、多孔質体の厚さBと基板の貫通孔の直径AからB/A2を算出した。
