摘要： When a mounting member employed for fine polishing of semiconductor substrates or glass substrates etc. is constituted of a combination of a sheet of continuous porous structure and a template, operating efficiency is lowered by the need to change the template; this is a factor raising production costs, and edge portions of the polishing workpiece get damaged by contact with the template, causing production of defective articles. By making the mounting member for polishing a member in which water repellence was conferred on at least a surface skin layer of a continuous sheet of porous structure, fine polishing without a template was made possible.
