Abstract
A shoe press belt includes a substrate, a wet paper web-side layer provided on the outer side of the substrate; and a shoe-side layer on the inner side; the wet paper web-side layer and the shoe-side layer are made from a high-polymer elastic material. The surface layer of the wet paper web-side layer includes concave water catching parts and land parts which are projecting parts occurring due to formation of the water catching parts. The occurrence of cracks in the surface part of the land part and the bottom part and corner parts of the water catching part of the shoe press belt is suppressed by setting the hardness of the surface part of the land part at a relatively higher value than the hardness of the bottom part of the water catching part. Thereby, occurrence of cracks in the surface part of the land parts and the bottom part of the water catching part in a shoe press belt having water catching parts and land parts in the surface layer of the wet paper web-side layer can be suppressed.
