The present invention relates to a car sheet using a polyester-based adhering powder comprising: a base layer which is formed of a polyester hard non-woven fabric; an adhering layer which is formed on a lower surface of the substrate layer and is formed of a dispersed polyester-based adhering powder; and a skin layer which is formed of polyester (PET) non-woven fabrics and in a lower surface of the adhering layer. The polyester-based adhering powder is made by grinding a low melting point copolymerized polyester resin which is copolymerized by a dicarbonic acid comprising 60-90 mole% of terephthalic acid and 10-40 mole% of isophthalic acid, and a diol comprising 60-100 mole% of ethylene glycol and 0-40 mole% of diethylene glycol. For the adhering powder, a glass transition temperature (Tg) is 50°C or more, a hardness (Shore D) is 80 or more, and a softening point is 80-140°C. The present invention is able to be easily recycled.
