PROBLEM TO BE SOLVED: To enhance the sensitivity of a magnetic resonator on a nuclear magnetic resonance signal. SOLUTION: A static magnetic field generation part 20 comprises a pair of magnets 21a and 21b fixed to a yoke 22, forming a magnetic circuit in its entirety. The generation part 20 is further equipped with a spacer 71 which is put on the magnets 21a and 21b. The spacer 71 is equipped with a dent part 71a for thereon mounting a measurement specimen 100 to shape the measurement specimen 100. A static magnetic field is formed around the generation part 20 where an equi-magnetic flux density surface exists having equal magnetic flux density. A resonance domain 100a appears in the density surface. With the measurement specimen 100 included in the measurement specimen 100 by bringing the measurement specimen 100 into line with the spacer 71, a nuclear magnetic resonance phenomenon is caused to take place over the whole of the density surface by using a transmission/reception coil 23.
