- the critical temperature is low, or the state of the crystal structure that does not enter the superconducting state), or the existence of the superconducting layer itself corresponding to the divided region 13a is absent, In the depth direction to the tape-shaped substrate 11, the material is not connected (the state in which there is no or all of the intermediate thin film layer below the divided region 13 a or the back surface of the tape-shaped substrate 11 is reached.
- the intermediate thin film layer below the divided region 13a and the part of the tape-shaped substrate are not present).

- the first embodiment four rows of divided regions 13a are formed, and five rows of superconducting layers 13b other than the divided regions 13a are formed. Therefore, this is the same as when five rows of superconducting tape wires are formed in which the divided regions 13a are not formed (having the same width as the width of the superconducting layer 13b in the direction orthogonal to the longitudinal direction). For this reason, the superconducting tape wire 10 is wide enough to form the divided regions 13a.
- the divided region 13a is not particularly limited to this configuration.
- a plurality of divided regions 13a are formed in parallel in the short direction of the superconducting layer 13 (the direction perpendicular to the longitudinal direction in FIG. 1, that is, the direction parallel to the one end 13c and the other end 13d) !, etc!
- the tape-like substrate 11 uses Ni (nickel) or Ni alloy-based oriented tape.
- the intermediate thin film layer 12 is made of a small amount of CeO (ceria) and YsZ (yttria stable zirconia).

- the divided region 13a is formed so as not to be in a superconducting state at the critical temperature of the superconducting layer 13b.
- the step (S40) is performed by a laser. Specifically, as shown in FIG. 3, a plurality of lasers (arrows in FIG. 3) are irradiated in parallel in the longitudinal direction of the superconducting layer 13 (four rows in FIG. 3). The portion irradiated with the laser becomes a divided region 13a. In other words, the superconducting layer 13 locally melts and solidifies in the part irradiated with the laser, resulting in a disordered crystallinity of that part (the crystal structure is disturbed compared to other parts). State).
- the part where the crystallinity is disturbed has a lower critical temperature than the other part (superconducting layer 13b), or the superconducting property is deteriorated from the other part so that it does not become the superconducting state.
- the superconducting material itself of the superconducting layer is scattered by the laser irradiation, and the material is lost. For this reason, the portion irradiated with the laser becomes the divided region 13a.
- the step (S40) is not particularly limited to being performed by a laser as long as the divided region 13a can be formed.
- the divided region 13a can change the crystallinity in the superconducting layer 13 by applying mechanical stress to the portion (for example, pressing a blade-shaped jig corresponding to the planar shape of the divided region 13a). May be formed.

- the surface protective layer is formed after the division region 13a is formed.
- the surface protective layer on the divided region 13a is in the same state as the surface protective layer on the superconducting layer 13b other than the divided region 13a.
- the step of forming the surface protective layer may be performed after the step of forming superconducting layer 13 (S30). In this case, after the surface protective layer is formed, the processing step (S40) is performed. In this case, the surface protective layer on the divided region 13a is in the same state as the divided region 13a.
- the operation of superconducting tape wire 10 in the first embodiment will be described.
- a voltage is applied between the one end 13c and the other end 13d of the superconducting tape wire 10 to cause a current to flow
- a certain condition e.g., to a temperature at which the superconducting layer 13b enters a superconducting state.
- a current can be passed in the superconducting state to the superconducting layer 13b in a portion other than the divided region 13a.
- the plurality of superconducting layers 13b can be regarded as conductive wires that are electrically independent from each other, and thus are equivalent to a state in which the plurality of superconducting wires are arranged in parallel.
- the operation of the superconducting tape wire 10 is not limited to the operation described above.
- the five superconducting layers 13b other than the divided region 13a can be connected in series. Specifically, it is electrically connected to another superconducting layer 13b in the vicinity at the end of each superconducting layer 13b.
