<p>The purpose of the present invention is to provide a method for manufacturing a laminated polishing pad wherein a polishing layer and a supporting layer are not easily peeled from each other even when the temperature of the pad becomes high due to long time polishing, and furthermore, wrinkles are not easily generated in the supporting layer. This method for manufacturing a laminated polishing pad includes a step wherein a stacked body is passed through between a pair of laminate rolls, said stacked body having a polishing layer and a supporting layer laminated with a hot-melt bonding member therebetween, and a laminated polishing sheet is manufactured by bonding the polishing layer and the supporting layer using the hot-melt bonding member. The method is characterized in that the stacked body has the ratio (TD1/TD2) of a polishing layer length (TD1) in the TD direction to a supporting layer length (TD2) in the TD direction constantly adjusted to 0.3 or more.</p> |
