Abstract:
A papermaking belt in which changes in surface properties of the resin layer upon use is suppressed, and a method for making the papermaking belt. Provided is a papermaking belt for use in a papermaking machine, including at least one resin layer including a resin, wherein the surface roughness after contacting the surface of the resin layer with a metal plate having a surface roughness equal to or less than 0.10 μm at a pressure of 100±3 kg/cm2 for 20 hours in warm water bathing at 70±5° C. is equal to or higher than 40% relative to the surface roughness of the surface of the resin layer in a wet state before the contact.
