PROBLEM TO BE SOLVED: To provide an automobile interior material having excellent abrasion resistance while maintaining tactile and easy processability of a needle punch unwoven fabric and a manufacturing method therefor.SOLUTION: There is provided an automobile interior material consisting of a polyester needle punch unwoven fabric to which a polycarbonate-based polyurethane resin is adhered, the polycarbonate-based polyurethane resin is obtained by chain extending an urethane prepolymer having an isocyanate group at a terminal, by reacting organic polyisocyanate and polyol containing polycarbonate diol represented by the formula (1) of a specific amount with molar ratio of a NCO group of the organic polyisocyanate and a OH group of the polyol of 1.5/1.0 to 1.1/1.0, with specific polyamine and adhesion amount of the polyurethane resin is 1 to 15 pts.mass based on 100 pts.mass of the unwoven fabric. Ris each independently a C4 to 8 alkylene group and n is an integer in a range of 1000 to 3500.SELECTED DRAWING: None
