Method for polishing using polishing pad provided with adsorption layer

A polishing method using a polishing pad including a specific adsorption layer. The polishing pad has an adsorption layer including a silicone including linear polyorganosiloxane having vinyl groups only at both ends, and the like. The polishing pad is fixed to a surface plate, and a product to be polished is pressed against the polishing pad, and simultaneously slid to polish the product to be polished. In this case, the surface roughness (Ra) of the surface plate is set to 0.01 to 0.7 μm, and the adsorption layer of the polishing pad is then adsorbed and fixed to the surface plate to perform polishing work. By adjusting the surface roughness of the surface plate as described above, a surface of the product to be polished can be inhibited from being unpredictably scratched or roughened. The method for adjusting the surface roughness of the surface plate is preferably a method in which a film having a surface roughness as described above is bonded to a surface of the surface plate.
