Sheet for suction and fixation, and method of producing the same
The sheet for suction and fixation according to the invention is a sheet for suction and fixation, constituted by including at least a porous sheet and used for suction and fixation of a member to be sucked, and the sheet for suction and fixation has a structure of a plurality of layers comprising a porous sheet provided on at least one side of the porous sheet with a particle layer constituted by including plastic particles, wherein the surface roughness (Ra) of the particle layer is not greater than 0.5 μm. A sheet for suction and fixation, which is continuous and long and excellent in surface smoothness, and a method of producing the same, can thereby be provided.
