An analytical method of the wood content of wood stock for car is provided to accurately analyze the each content of base polymer and wood of the wood stock consisting of the polypropylene and organic cellulose, thereby preventing property degradation of material. The analytical method of the wood content of car wood stock comprises the steps of: setting up the wood stock material specimen which is the composite material in which the polypropylene and Wood are contained to have the size to be installed in the thermogravimetric analyzer(TGA) equipment; and subjecting the wood stock to the temperature increase and decrease according to the pyrolysis execute procedures of the thermogravimetric analyzer equipment, and simultaneously controlling the air condition of the furnace to calculate the content of the wood stock, wherein the pyrolysis execute procedures include the steps of: increasing the temperature of the furnace from 30 deg. C to 400 deg. C under nitrogen condition at the speed of 20 deg. C/min; maintaining the temperature at 400 deg. C for 20 minutes; increasing the temperature to 580 deg. C at the speed of 20 deg. C/min; and changing the condition of furnace with oxygen, and increasing the temperature to 850 deg. C at the speed of 20 deg. C/min.
