Abstract
Magnetoresistive effect elements are provided with an element unit having an elongated shape in which an element length Lis formed to be longer than an element width W. The element unit has a fixed magnetic layer and a free magnetic layer laminated via a non-magnetic layer on the fixed magnetic layer. A magnetism direction of the fixed magnetic layer faces an element width direction (Y direction) of a sensitivity axis direction. First soft magnetic bodies formed to have a width size Wand a length size Lare arranged in a non-contact manner on both lateral sides of the magnetoresistive effect element. The length size Lis longer than the element length L, and the first soft magnetic body has an extension part extending in an element length direction from both sides in the element length direction of the element unit.
