Abstract

The present invention relates to a stacking structure of a superconducting wire. The present invention provides a superconducting wire in which a metal substrate, a buffer layer, a superconducting layer, and a stabilizing layer are stacked, the superconducting wire including: a plurality of wedges which penetrates through the superconducting layer and the buffer layer to connect the stabilizing layer and the metal substrate. According to the present invention, it is possible to provide the superconducting wire of which mechanical strength is improved to have high resistance against to deterioration or delamination. Further, the present invention may provide the superconducting wire which is self-protectable against a quench phenomenon. Further, the present invention may provide the superconducting wire which is suitable for application of a high magnetic field.
