A process for producing ultra-fine long fiber sheet by using an ultra-fine fiber-generating type long fiber is provided. The production process comprises a step of forming a long fiber web consisting of an ultra-fine fiber-generating type long fiber whose at one component is a water-soluble thermoplastic polyvinyl alcohol-based resin, a step of subjecting the long fiber web to an entangling treatment to give a long fiber entangled sheet, a step of obtaining a long fiber shrinkage sheet by the shrinking treatment of the long fiber entangled sheet, and a step of obtaining a ultra-fine long fiber entangled sheet by transforming the ultra-fine fiber-generating type long fiber into an ultra-fine long fiber by the ultra-fine fiberization treatment of the long fiber shrinkage sheet. The entangling treatment is carried out such that the interlayer peeling strength of the long fiber entangled sheet is 2 kg/2.5 cm or more, and the shrinking treatment is carried out such that the surface shrinkage is 35% of more.
