Claim 14:
15. A superconducting wire comprising:
a first superconducting wire including a first superconducting layer;
a second superconducting wire including a second superconducting layer;
a third superconducting layer having a first surface and a second surface facing the first surface; and
a connection layer provided between the first superconducting layer and the third superconducting layer and between the second superconducting layer and the third superconducting layer, and the connection layer including a first substance containing a rare earth element (RE), barium (Ba), copper (Cu), and oxygen (O) and a second substance containing at least one metal element selected from the group consisting of silver (Ag), aluminum (Al), indium (In), copper (Cu), tin (Sn), and zinc (Zn),
wherein the first superconducting layer and the second superconducting layer are located on a side of the first surface of the third superconducting layer,
a portion of the second substance is in contact with the first superconducting layer and the third superconducting layer,
the portion of the second substance is continuous between the first superconducting layer and the third superconducting layer,
a different portion of the second substance is in contact with the second superconducting layer and the third superconducting layer, and
the different portion of the second substance is continuous between the second superconducting layer and the third superconducting layer.
