Abstract
A connection structure for a superconducting layer according to an embodiment includes a first superconducting layer; a second superconducting layer; and a connection layer disposed between the first superconducting layer and the second superconducting layer, the connection layer including crystal grains containing a rare earth element (RE), barium (Ba), copper (Cu), and oxygen (O), the crystal grains having a grain size distribution including a bimodal distribution. The bimodal distribution includes a first distribution including a first peak and a second distribution including a second peak. A first grain size corresponding to the first peak is larger than a second grain size corresponding to the second peak. Among the crystal grains, crystal grains having a grain size corresponding to the first distribution include a crystal grain having a plate shape or a flat shape.
