Abstract
Disclosed is a nubuck-finished leather-like sheet including a non-woven fabric that is an entangled body of ultrafine filaments, wherein the non-woven fabric includes a napped surface having napped fibers formed thereon, and the napped fibers are fixed to an acrylic resin on the napped surface while being laid down. Preferably, the acrylic resin is present so as to retain voids in the napped surface, while being made malleable.
