PURPOSE: To provide a napped leather-like sheet which has such a slippery smooth surface touch as that of the suede or nubuck of natural leather, suitable stiff flexibility, an excellent hand, and a high-grade appearance, and to provide a method for producing the same. CONSTITUTION: This napped leather-like sheet which comprises an interlaced nonwoven fabric comprising superfine fibers and an elastic polymer contained in the nonwoven fabric and on whose one side or both sides the naps comprising the superfine fibers are formed, is characterized in that a silk protein-based substance and a softener are imparted to the surface portion of the napped side. A method for producing the napped leather-like sheet, comprising coating the surface of the napped leather-like sheet with a liquid containing the silk protein-based substance and the softener by a gravure printing method or a spray method. 극세 섬유로 된 낙합부직포와 그 내부에 함유된 탄성중합체로 이루어지고 또한 일면 또는 양면에 극세 섬유로 만들어진 입모를 형성시킨 입모 피혁형 시트로서, 입모면의 표면 부분에 실크 프로테인계 물질과 유연제를 부여한 입모 피혁형 시트, 및 실크 프로테인계 물질과 유연제를 함유한 액을 그라비어 인쇄방식 또는 스프레이 방식으로 입모 피혁형 시트 표면에 도포하여 상기 입모 피혁형 시트를 제조하는 제조방법.
