PROBLEM TO BE SOLVED: To provide a probe coil for an NMR (nuclear magnetic resonance) apparatus having a high Q-value and a high S/N ratio, in which the probe coil is composed of one of a saddle type, a birdcage type, a Helmholtz type, a one-turn type, a solenoid type, a pancake type, and so forth, or the combination of the coils having any shapes of respective types. SOLUTION: In the superconductive probe coil for the NMR apparatus, a magnesium diboride superconductor is formed on the surface of a flexible organic polymer material substrate. The probe coil is composed of the organic polymer material in which hydrogen is not included in the molecular structure of the substrate, or all or a part of the hydrogen contained in the molecule of the substrate material is replaced with deuterium.
