A proton conductor includes a metal ion, an oxoanion, and a molecule capable of undergoing protonation or deprotonation, in which at least one of the oxoanion and the molecule capable of undergoing protonation or deprotonation coordinates to the metal ion to form a coordination polymer. The oxoanion is preferably a monomer. The oxoanion is exemplified by at least one selected from the group consisting of phosphate ion, hydrogenphosphate ion, and dihydrogenphosphate ion. The molecule capable of undergoing protonation or deprotonation is exemplified by at least one selected from the group consisting of imidazole, triazole, benzimidazole, benzotriazole, and derivatives thereof.

A high-resolution solid-state NMR spectrometer which can measure a disklike sample. The spectrometer includes: a stator having an air bearing disposed within the static magnetic field, the rotor being disposed in the stator; and an engaging mechanism mounted in a one-end portion of the rotor and detachably holding a sample holder that holds the disklike sample.
