This displacement detection device is provided with a magnetic field generation unit, a first soft magnet, a second soft magnet, and a magnetic detection element. The magnetic field generating section expands along a plane orthogonal to the first direction, and has a first portion and a second portion. The first soft magnet is disposed so as to overlap with the first portion as a whole in the first direction, and the second soft magnet is disposed so as to overlap with the second portion as a whole in the first direction. The magnetic detection element is disposed in a region between the first soft magnet and the second soft magnet, and the magnetic field generated by the magnetic field generation unit is applied to the magnetic detection element. The magnetic field generating unit, the first soft magnet, and the second soft magnet are provided so as to be integrally rotatable about a rotation axis extending in a first direction with respect to the magnetic detection element.

    本发明的位移检测装置具备磁场产生部、第一软磁体、第二软磁体和磁检测元件。磁场产生部沿着与第一方向正交的平面扩展,并且具有第一部分和第二部分。第一软磁体配置成在第一方向上与第一部分整体互相重叠,第二软磁体配置成在第一方向上与第二部分整体互相重叠。磁检测元件配置在第一软磁体与第二软磁体之间的区域,被施加由磁场产生部形成的磁场。磁场产生部、第一软磁体和第二软磁体设置为可以对磁检测元件以旋转轴为中心一体旋转,旋转轴在第一方向上延伸。
