The sheet body includes a top surface, a plurality of foamed pores, and a plurality of surface holes or at least one surface groove. The top surface is used for mounting a workpiece. The foamed pores are disposed in the interior of the sheet body. The surface holes or the surface groove have opening on the top surface but does not communicate with the foamed pores.
