<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnetic field detection apparatus having spin valve elements on a substrate. <P>SOLUTION: The method for manufacturing the magnetic field detection apparatus includes: a step for preparing a substrate 1; a step for forming spin valve elements 11 to 14 each including a fixed layer, an insulating layer and a free layer on the substrate; a step for forming collection magnetism areas 21, 22 in the vicinity of each spin valve element; and a magnetization step for magnetizing the free layer of each spin valve element by applying a magnetic field of an H direction to the substrate. The magnetization step applies a magnetic field of a predetermined direction different from the H direction to each spin valve element by the collection magnetism areas 21, 22 to magnetize the spin valve element in the predetermined direction different from the H direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
