The present invention provides a method of manufacturing a sheet article by an environmentally-conscience manufacturing process, the sheet article having an elegant appearance, a soft feel, and good wear resistance even when a polyvinyl alcohol aqueous solution which has a low degree of polymerization and low viscosity and traditionally has high solubility to water is used. In this method for manufacturing a sheet article, the following steps 1 to 4 are performed in order. 1. A polyvinyl alcohol applying step of applying a polyvinyl alcohol aqueous solution to a fibrous substrate that is mainly composed of microfiber expression type fiber, the polyvinyl alcohol aqueous solution being an aqueous solution of polyvinyl alcohol having a saponification degree of 90% or more and an rrr composition abundance ratio in a tacticity evaluation measured by 13C-NMR in a heavy water solvent of 14.5% or more, to thereby apply 0.1 to 50 mass% of the polyvinyl alcohol to fiber mass contained in the fibrous substrate. 2. A microfiber expression step. 3. A polyurethane applying step. 4. A polyvinyl alcohol removing step.
