PROBLEM TO BE SOLVED: To provide an NMR device capable of multiple resonance measurement. SOLUTION: This device uses a superconducting reception coil, a transmission coil 12, and an additional coil 55 constituted of four current loops 62-1 to 62-4, wherein the directions of currents flowing in inside loops 62-2. 62-3 and in outside loops 62-1, 62-4 are reverse directions. The additional coil 55 and the transmission coil 12 are arranged so that the direction of a high frequency magnetic field generated in the coil center when feeding the additional coil 55 becomes approximately the same as the direction of a high frequency magnetic field generated in the transmission coil center when feeding the transmission coil 12. A current loop of the transmission coil 12 is arranged approximately on the middle between the inside loops and the outside loops of the additional coil 55 wherein the directions of the currents flowing in the inside loops and in the outside loops are reverse directions.
