PURPOSE:To obtain a leather-like molded article close to natural leather characteristics, by heating leather powder in steam, drying the leather powder into a water content in a specific range, grinding into a specific fine particulate state, blending the fine powder with a thermoplastic resin containing gelatin and molding into a sheetlike state. CONSTITUTION:First a leather material is heated in steam, dried into <=4% water content in the leather and ground into a fine particulate state having particle diameters passing through 30 mesh sieve free from entanglement. 70-10wt% of the leather powder is blended with 30-90wt% thermoplastic resin compound (e.g. vinyl chloride, etc.) containing 5-30wt% gelatin (to promote fluidity) by weight ratio and molded into sheetlike or filmlike shape by calender rolls to give a leather-like molded article. Then the sheet is embossed, rubbed and embossed or napped so that a leather-like molded article matching any of various purposes can be obtained.
