<P>PROBLEM TO BE SOLVED: To provide an NMR probe which can measure an NMR spectrum with high sensitivity with a high SN ratio constantly by eliminating the replacement of the NMR probe for a plurality of nuclides having different resonance frequencies in an object under measurement and the adjustment of NMR resolution associated with the replacement. Ž<P>SOLUTION: An antenna coil of an NMR probe includes a plurality of loops which are arranged in series mutually, inter-loop connecting parts arranged for connecting the plurality of loops, and switches which are arranged in the inter-loop connecting parts and can switch between the interruption and passage of a high-frequency current. The outer part, the inner part, and the intermediate part between both of the loops and the inter-loop connecting parts are formed of three kinds of nonmagnetic substances, respectively. The cross section perpendicular to the static magnetic field of the outer part, intermediate part, and inner part of the nonmagnetic material constituting the loops and the inter-loop connecting parts is set so that the sum of the product of the cross section and the volume susceptibility of each nonmagnetic material becomes nearly zero.
