Abstract
A magnetic field measuring element includes a Superconducting QUantum Interference Device magnetic sensors, the first sensor disposed either on a second plane perpendicular to a first plane including a coil surface of the third sensor and which includes the center of the third sensor, or in the vicinity of the second plane, and a second sensor disposed either on a third plane perpendicular to the first plane and the second plane, or in the vicinity of the third plane. The center of the first sensor is present either on a straight line which passes through the center of the third sensor and is perpendicular to the first plane, or in the vicinity of said straight line, and the center of the second sensor is present in a position displaced from a line joining the center of the third sensor and the center of the first sensor.
