The invention relates to a door frame for a vehicle having improved anti-corrosive performance, and a method of manufacturing the door frame. The door frame may includes: a three-stage superimposed portion which has a structure in which an upper steel plate layer, an intermediate steel plate layer, and a lower steel plate layer are superimposed, and in which a sealer for anti-corrosive performance is applied between the upper steel plate layer and the intermediate steel plate layer; and a curved portion which is formed at an upper side of the intermediate steel plate layer at a first end of the three-stage superimposed portion to prevent the applied sealer from being exposed to the outside, thereby improving anti-corrosive performance, and a method of manufacturing the door frame. 本发明涉及一种具有改进的防腐蚀性能的车辆的门框及其制造方法。该车辆的门框可以包括：三级叠合部分具有上钢板层、中间钢板层和下钢板层叠合的结构，并且用于防腐蚀性能的密封材料涂布在上钢板层和中间钢板层之间；曲线部分形成在中间钢板层的上侧三级叠合部分的第一端处，以防止所涂布的密封材料暴露在外面，由此改进防腐蚀性能。
