PROBLEM TO BE SOLVED: To provide an NMR probe for high temperature measurement capable of measuring an NMR at temperature of 1,500°C or higher. SOLUTION: The NMR probe for high temperature measurement, which is inserted and arranged from below in a vertical hole provided along the center axis of a superconducting magnet, includes the followings: (1) a detection coil provided in a central space; (2) a cylindrical RF shield provided around the central space; (3) a cylindrical heater provided around the outer periphery of the RF shield; (4) a cylindrical reflection means which is arranged around the outer periphery of the heater and which reflects radiant heat going outwardly from the heater; (5) a cylindrical thermal insulation material and cylindrical cooling means which are arranged around the outer periphery of the reflection means; (6) a relay connection means which relays and connects a lead wire from the detection coil to an electric circuit using a metal fitting equipped with a heat dissipation means.
