Abstract
There is disclosed an NMR (nuclear magnetic resonance) probe having a support that produces no NMR background signal, has heat resistance, does not distort homogeneous static magnetic field, has a low dielectric loss, and is easy to machine. The NMR probe has a sample bobbin on which a detector coil is mounted, as well as the support described above. The support holds the sample bobbin. The support is plated with a metal to prevent generation of NMR background signals. The support has a bushing equipped with a hole having a diameter substantially equal to that of an extraction line extending from the detector coil. The hole passes the extraction line. The bushing is made of an insulative material of a low magnetic susceptibility. Thus, leakage of air from the hole is prevented. At the same time, the support and the extraction line are electrically insulated from each other.
