Abstract: 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.

Abstract: An electronic component includes; a magnetic-body core having a plate-shaped portion and a core portion which extends from an upper surface of the plate-shaped portion; a winding wire which includes a wound portion wound by a rectangular wire into an Edgewise winding form and two non-wound portions extending from the wound portion to two distal ends, and the core portion is inserted through the wound portion; and a magnetic exterior body which covers at least the wound portion and the core portion. The two non-wound portions are respectively arranged along a bottom surface and at least one of the side surfaces of the plate-shaped portion. Parts of the two non-wound portions arranged along the bottom surface are electrodes.
