PURPOSE: An oil tone artificial leather sheet having a blend of an oily substance and a supporting polymer on part or all of the nap surface of a napped sheet comprising a non-woven fabric of microfine fibers and polyurethane existing in the non-woven fabric is provided, which has a high-class appearance and smooth texture and feeling close to natural leather and is useful when applied to the manufacture of shoes or the like. CONSTITUTION: This artificial leather sheet is prepared by coating a blend of a supporting polymer and an oily substance of viscosity 50 to 10,000 mPa.s at 30 deg.C in a weight ratio of 1 to 20 on part or all of a nap surface of a napped sheet comprising a non-woven fabric of microfine fibers having 0.3 denier or less and polyurethane. The supporting polymer is a block copolymer having a polymer block(A) comprising a vinyl aromatic compound and a polymer block(B) comprising conjugated diene, or a hydrogen additive thereof. 극세섬유로 이루어진 락합부직포에 폴리우레탄이 함유되고 또한 적어도 편면의 일부 또는 전면에 이 극세섬유로 이루어진 입모가 존재하고 있는 입모시트의 입모면의 일부 또는 전면에 30℃ 에서의 점도가 50 내지 10000 mPaㆍs 의 유상물질과 그 지지체로 이루어진 배합물이 존재하고 있는 오일풍 피혁형 시트는 고급스러운 외관을 지니고, 또한 천연피혁과 동등한 유연한 질감, 촉감을 겸비하고 있어 신발등에 대한 응용에 유용하다.
