PURPOSE: A manufacturing method of a liquid crystal polyester composition is provided to have excellent mechanical strength, and to provide liquid crystal polyester composition. CONSTITUTION: A manufacturing method of a liquid crystal polyester composition comprising nanostructured hollow-carbon material and liquid crystal polyester comprises a step of melt-mulling 85-99 parts by weight of polyester and 1-15 parts by weight of nanostructured hollow-carbon material based on 100.0 parts by weight of total weight of the nanostructured hollow-carbon material and the liquid crystal polyester under a shearing rate of 1,000-9,000 /second. The nanostructured hollow-carbon material comprises a carbon part and a hollow part. A part or whole part of the hollow part has a structured surrounded by carbon.
