Disclosed are a car interior sheet manufactured by using a defective product (defective hygiene product) among hygiene products such as tissues or diapers including wet-strength paper made of pulp including plastic or super absorbent polymer (SAP). The car interior sheet is manufactured by attaching surface layers such as a nonwoven fabric to both surfaces of a base layer thereof including 30-50 weight % of a pulverized material, 5-15 weight % of additives, and 30-50 weight % of thermoplastic resin. The car interior sheet represents a low manufacturing cost, and does not generate environmental hazardous materials. The car interior sheet represents superior impact resistance at high and low temperatures, has a superior moisture absorption rate due to the SAP, so that the car interior sheet is rapidly dried after the moisture has been absorbed.
