Abstract: Disclosed are a non-oriented electrical steel sheet and a method for manufacturing same, wherein the texture of the electrical steel sheet is optimized after cold rolling by controlling the temperature and atmosphere of decarburization annealing and final annealing, and thus excellent iron loss can be obtained even at low temperatures. In addition, disclosed are a non-oriented electrical steel sheet and a method for manufacturing same, wherein processes, from the processing of the electrical steel sheet into motor component to a final heat-treatment, are improved to enhance the strength of the texture aligned in the direction of easy magnetization and thereby improve the magnetic characteristics of the steel sheet.
