Patent ID: 7138801

Claim:
A nuclear magnetic resonance spectrometer comprising: means for generating a prescribed static magnetic field; and a probe placed in the magnetic field, in which a sample tube containing sample to be measured can be inserted or removed, the magnetic field generating means comprising: a superconducting magnet split in half which allows the probe to be inserted vertically or horizontally to a magnetic field generated by the superconducting magnet, the probe comprising: a plurality of coil substrates on which a superconducting thin film coil with a shape of partially open 1 turn coil is formed; and a wiring substrate on which line patterns of superconducting thin films with a prescribed circuit pattern are formed, wherein the plural coil substrates and the wiring substrate are coupled so as to form a prescribed circuit configuration by capacitively coupling the open ends of the superconducting thin film coil and part of the line pattern of superconducting thin film; and wherein the edges of the plural coil substrates coupled with the wiring substrate are fixed by a side holding plate coupled with the other edges of the coil substrates, and a side holding plate provided to a side surface of the wiring substrate.
