Abstract
In a magnetic sensor, a pinned layer covers a wiring layer on a side opposite to a substrate with respect to the wiring layer and includes a bent portion having a bent shape in cross section. Free layers are arranged on a side opposite to the substrate with respect to the pinned layer. The size of the free layers in a planar direction is set to a size smaller than the size of the pinned layer in the planar direction. A magnetic field leaking from the pinned layer may form a closed loop adjacent to the substrate, that is, on a side opposite to the free layers with respect to the substrate. Therefore, influence of the magnetic field leaking from the pinned layer on the free layers can be restricted.
