摘要： Disclosed herein is a method of preparing a MgB2 superconducting wire and the MgB2 superconducting wire prepared thereby. The method comprising rolling a raw powder by using a powder rolling method. According to the method of the present invention has an effect of increasing an effective area where superconducting current can flow by improvement of the connectivity of a MgB2 superconducting powder and achievement of high density through a powder rolling process, and maintaining an uniform current value even in a large length because of the improvement of the connectivity.
