An embossing belt for a paper machine, intended to run through a press section in the paper machine together with a fibrous web and produce an embossment thereof in the press section, and to transfer the embossed fibrous web from the press section directly to and through a transfer means in the dryer section of the paper machine. The embossing belt is essentially impermeable and comprises a rear layer (33) and a web-contacting layer (34), which has a large number of uniformly distributed depressions (35) and, positioned therebetween, surface portions (36) for forming a corresponding relief pattern in the fibrous web passing through the press section.
