1. A high-frequency magnetic field generating device, comprising:
a plate coil; and
a high-frequency power supply that generates microwave current that flows in the plate coil;
wherein (a) one edge line part in a top end side and (b) one edge line part in a bottom end side among four edge line parts of the plate coil act as 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;
wherein the plate coil comprises a circular part, and two penetrating holes formed in the circular part; and
the two penetrating holes are formed such that a light beam with which the electron spin resonance material is irradiated enters from one of the two penetrating holes, and the light beam exits through the other of the two penetrating holes.
