    摘要： A magnetic resonance member 1 includes a diamond crystal including plural diamond nitrogen vacancy center, and a high-frequency magnetic field generator 2 applies magnetic field of microwave to the magnetic resonance member 1. The aforementioned plural diamond nitrogen vacancy centers include diamond nitrogen vacancy centers arranged in directions of predetermined plural axes among four axes that indicates four connection directions of carbon atoms in the diamond crystal; and the aforementioned magnetic resonance member 1 is arranged in a direction that provides a substantially largest sensitivity of the measurement target magnetic field in the diamond nitrogen vacancy centers arranged in the predetermined plural axes.

    摘要： A magnetic resonance member 1 includes a crystal structure and is capable of electron spin quantum operations with microwaves of different frequencies corresponding to arrangement orientations of a vacancy and an impurity in a crystal lattice. A magnetic field transmission unit 4 senses a measurement target magnetic field at plural measurement positions different from each other, and applies application magnetic fields corresponding to the measurement target magnetic field sensed at the plural measurement positions to the magnetic resonance member 1 along respective different directions corresponding to the aforementioned arrangement orientations. A measurement control unit 21 controls a high frequency power supply 12, and determines detection values detected by a detecting device (an irradiating device 5 and a light receiving device 6) of the physical phenomena corresponding to the plural measurement positions. A calculation unit 22 calculates the measurement target magnetic field at the plural measurement positions on the basis of the detection values.
