Method for manufacturing polishing pad

A method for manufacturing a laminated polishing pad, comprising the steps of:

• preparing a cell-dispersed urethane composition by a mechanical foaming method;
• discharging a light transmitting region-forming material such that the material is deposited in and on through holes, while feeding a cushion layer having continuously or intermittently provided through holes;
• continuously discharging said cell-dispersed urethane composition onto a part of said cushion layer where the light transmitting region-forming material is not provided;
• laminating a face material on the discharged light transmitting region-forming material and cell-dispersed urethane composition;
• curing the light transmitting region-forming material and the cell-dispersed urethane composition, while controlling their thickness to be uniform, so that a long laminated sheet comprising a light transmitting region and a polishing region integrated therewith is formed;
• and
• cutting the long laminated sheet.
