PROBLEM TO BE SOLVED: To provide a method for production by which a liquefied resin raw material composition can be obtained from a woody material in a state in which components are easily separated. SOLUTION: The method for producing the liquefied resin raw material composition includes an acid decomposition step of adding an acid to the woody material and decomposing the woody material with the acid. In the method, the acid decomposition step is carried out in the presence of an aromatic glycol ether. The resultant liquefied resin raw material composition provides even a material such as lignin in which separation is conventionally difficult can be obtained in a liquefied state in which separation and purification are easily performed. Since the amount of the acid added in the acid decomposition step can be small, the amount of water, a neutralizing agent and a solvent etc., in treatment in a post-process can be reduced. The resultant liquefied resin raw material composition can be regulated to a low salt concentration, the composition can sufficiently be used as a raw material for various chemicals.
