PROBLEM TO BE SOLVED: To provide an NMR device capable of reducing radiation damping only by a fundamental constitution of the NMR device. SOLUTION: The electric length between the first amplification means and a coil means and the electric length between the second amplification means and the coil means are set so as to have the length by which the phase of a reflected wave becomes a reverse phase to the phase of an NMR signal at the detection time, when the NMR signal detected by the coil means is propagated to the first amplification means or the second amplification means through a switching means, and a part of the NMR signal is reflected by the first amplification means or the second amplification means and returned to the coil means.
