    • Magnetoresistive effect elements are provided with an element unit having an elongated shape in which an element length L1 is formed to be longer than an element width W1. 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 W2 and a length size L2 are arranged in a non-contact manner on both lateral sides of the magnetoresistive effect element. The length size L2 is longer than the element length L1, 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.
    • 磁阻效应元件设置有具有细长形状的元件单元,其中元件长度L1形成为长于元件宽度W1。 元件单元具有固定磁性层和通过固定磁性层上的非磁性层层叠的自由磁性层。 固定磁性层的磁方向与感光度轴方向的元件宽度方向(Y方向)相对。 形成为具有宽度尺寸W2和长度尺寸L2的第一软磁体以非接触方式布置在磁阻效应元件的两个侧面上。 长度尺寸L2比元件长度L1长,第一软磁体具有在元件单元的元件长度方向上的两侧沿元件长度方向延伸的延伸部。
