PROBLEM TO BE SOLVED: To provide a probe coil for an NMR device, which is capable of transmitting and receiving high-frequency radio waves and has a Q factor and an S/N ratio which are both improved. SOLUTION: As one of means for solving the problem, the NMR device probe coil is formed into a solenoid composed of a magnesium diboride superconductor. Or, as the other means, the NMR device probe coil is composed of a plurality of magnesium diboride super conductor coils which are connected together in series. Or, as the other means, the NMR device probe coil is composed of the magnesium diboride superconductor in which metal is mixed. Furthermore, as the other means, the NMR device probe coil is composed of a single metal or an alloy of a plurality of metals selected from gold, silver, palladium, nickel, niobium, titanium, tin, beryllium, tungsten, and cobalt.
