A negative electrode manufacturing device for lithium secondary battery that is capable of simultaneously performing crystal surface orientation and pre-drying of a carbon-based negative electrode active material at an edge end of a negative electrode slurry is provided. The negative electrode manufacturing device provides a drying part using light at an edge of a magnetic part that aligns the crystal surface of the carbon-based negative electrode active material. A negative electrode manufactured by the device has a high orientation of the crystal surface of the carbon-based negative electrode active material contained in a sliding region of the negative electrode active layer, and high uniformity of orientation between the sliding region and a flat region of the negative electrode active material.
