PROBLEM TO BE SOLVED: To provide a pressing device taking away air without unevenness and in a short time by arranging a sheet between a surface plate surface and a second plate member. SOLUTION: A Teflon-coated glass fiber or a Kepler fiber sheet 33 is in- serted between a surface plate 14 and a lower part glass substrate 11. Then, when an LCD cell 23 is stuck using the pressing device 22, the LCD cell 23 is set on the surface plate 14 through the sheet 33 consisting of the Teflon- coated glass fiber or the Kepler fiber. Then, a cylindrical clamp 15 attaching an elastic mat 16 is set on the surface plate 14 through an 0 ring 17. At this time, an upper part heat source 20 and a lower part heat source 21 hold sufficient intervals A1, B1 so as not to heat the LCD cell 23. Then, vacuum exhaust of tightly sealed space 24 is performed from a vacuum source 18, and the LCD cell 23 is pressed by atmospheric presser 19 through the elastic mat 16.
