PROBLEM TO BE SOLVED: To realize a solenoid coil applicable to the superconducting magnet used in a high-resolution NMR analyzer, etc., by an oxide superconducting wire, and to provide the usable oxide superconducting wire as the raw material of such solenoid coil. SOLUTION: An oxide superconducting multicore wire with many buried Bi based 2212 type oxide superconducting filaments 1 in a silver or silver alloy sheath material 2, the thicknesses of whose filaments 1 are all made not larger than 50μm. By such a multicore wire, an applicable solenoid coil to the superconducting magnet used in a high-resolution NMR analyzer, etc., can be realized. |
