Abstract
A high-frequency magnetic field generatorapplies microwave to a magnetic resonance member. A magnetapplies a static magnetic field to the magnetic resonance member. An irradiating deviceirradiates the magnetic resonance memberwith incident light of a specific wavelength. An FTsenses a measurement target magnetic field using a primary coiland applies an application magnetic field corresponding to the sensed measurement target magnetic field to the magnetic resonance memberusing a secondary coil. A pillar-shaped light guide memberguides the incident light to the magnetic resonance member, and a pillar-shaped light guide memberguides fluorescence that the magnetic resonance memberemits from the magnetic resonance member. Further, the magnetic resonance memberis arranged between an end surface of the light guide memberand an end surface of the light guide memberin a hollow part of the secondary coilof the FTand in a hollow part of the aforementioned magnet
