A polishing pad has a working layer provided with an abrasive powder, an attaching layer for attaching a pad to a polishing head of a power tool, and a connection layer which connects the working layer with the attaching layer, the connection layer being located between the working and the attaching layer and having a peripheral region which is thinner and also a central region which is thicker than the peripheral region and therefore has an increased elasticity so that during polishing an elasticity of a central portion of the working layer is increased.
