发明名称	MAGNETIC FIELD SENSOR AND METHOD OF MEASURING MAGNETIC FIELD USING THE SAME
摘要	PROBLEM TO BE SOLVED: To detect a magnetic field with high reliability by enabling determination of positive and negative directions. SOLUTION: A magnetic field sensor includes: a ferromagnetic thin film 3; power feed sections 5A, 5B including input/output terminals for supplying an element current to the ferromagnetic thin film; and detection sections 5C, 5D for detecting voltage of the ferromagnetic thin film (between end sections) in a direction orthogonal to the direction of the element current. The ferromagnetic thin film is formed symmetrically to the direction of the element current. COPYRIGHT: (C)2011,JPO&INPIT
