Zusammenfassung:The present invention pertains to a leather-like sheet which comprises a fiber base material, an intermediate resin layer laminated on one surface of the fiber base material, and a surface resin layer laminated on the intermediate resin layer, and wherein: the surface resin layer contains a polyether-based polyurethane and spherical microparticles having heat resistance at 200 DEG C, and the content ratio of the spherical microparticles is 5-40 mass%; the specific heat of the spherical microparticles is 0.95 kJ/(kgK) or more, the particle diameter D50 (median diameter) at a cumulative distribution of 50 vol% is 2.5-10 [mu] m, and the particle diameter D10 at a cumulative distribution of 10 vol% satisfies particle diameter dispersity D50/D10 < = 3. 本发明涉及一种皮革状片,其具备:纤维基材、层叠于纤维基材的一面的中间树脂层、以及层叠于中间树脂层的表面树脂层,其中,表面树脂层含有聚醚类聚氨酯及具有200℃的耐热性的球状微粒,并且球状微粒的含有比例为5~40质量%,球状微粒的比热为0.95kJ/(kg·K)以上,累积分布50体积%时的粒径D50(中值粒径)为2.5~10μm,并且累积分布10体积%时的粒径D10满足粒径分散度D50/D10≤3。
