A field being measured is applied to a measurement magnetic resonance member (1) but is not applied to a reference magnetic resonance member (1R). High-frequency magnetic field generators (2, 2R) perform an electron spin quantum operation for the measurement magnetic resonance member (1) and the reference magnetic resonance member (1R) using measurement microwave and reference microwave, respectively. A power divider (11a) distributes high-frequency current from a high-frequency power supply (11) to the high-frequency magnetic field generators (2, 2R). A light distributor (21) distributes excitation light from a light emitting device (12) to the measurement magnetic resonance member (1) and the reference magnetic resonance member (1R). Light receiving devices (13, 13R) receive fluorescent light from the measurement magnetic resonance member (1) and the reference magnetic resonance member (1R), respectively, and generate fluorescent light sensor signals, respectively. An arithmetic processing unit (30) derives a measurement value on the basis of the fluorescent light sensor signals.

Method For Treating Living Body Using Electrical Stimulator
Provided is a method for treating a living body using an electrical stimulator including a base wire having a core wire and an outer winding wire wound around the core wire. An annulus is formed by winding the base wire in a loop shape. A first end of the core wire is electrically connected to a first end of the outer winding wire. A second end of the core wire is connected to a first terminal of an external circuit. A second end of the outer winding wire is connected to a second terminal of the external circuit. The method includes holding the living body or a part of the living body of a subject in the annulus and generating an alternating current in the external circuit for a therapeutically effective time period to apply an electrical stimulation to the living body or the part of the living body.

A high-frequency magnetic field generating device includes two coils arranged with a predetermined gap in parallel with each other, the two coils (a) in between which electron spin resonance material is arranged or (b) arranged at one side from electron spin resonance material; a high-frequency power supply that generates microwave current that flows in the two coils; and a transmission line part connected to the two coils, that sets a current distribution so as to locate the two coils at positions other than a node of a stationary wave.
