Abstract
A press belt with occurrence of pinholes remarkably reduced as well as a manufacturing method of the press belt are provided. The press belt includes a reinforcing base material containing multifilaments that are impregnated with a bundling agent and an elastic material in which the reinforcing base material is buried. The manufacturing method is a method of manufacturing the aforementioned press belt. The reinforcing base material is preferably made of a woven fabric and the bundling agent preferably contains as its main component thermosetting resin. As the bundling agent, a bundling agent containing as its main component urethane-based resin is suitably used. For the reinforcing base material, organic fibers are preferably used. The bundling agent is preferably applied in the form of emulsion to the multifilaments or the reinforcing base material.
