There is provided a superconducting cable having wide-width superconducting strip lines. The superconducting cable having wide-width superconducting strip lines includes, from the center of the cable, a former, a superconducting layer, an electronic insulation layer, and a super not conducting shield layer. The superconducting layer is formed as a plurality of superconducting strip lines spirally wound around the circumference of the former, and each of the strip lines has a rectangular cross section. Further, the strip lines are, respectively, made up of a wide-width strip line of which the ratio of the width to the thickness is within the range of 20 to 30. According to the embodiment herein, because the superconducting layer is formed with wide- width superconducting strip lines having the aspect ratio of 20 to 30, the strip lines may adhere closely to the former and be wound around the circumference of the former. Further, the gap between neighboring strip lines may be reduced. Moreover, the cable accordi
