Abstract

A position detection device includes: a first magnetic field generator generating a first magnetic field; a driver opposed to the first magnetic field generator in a first-axis direction; and a magnetic field sensor detecting the first magnetic field. The driver causes the first magnetic field generator to move in a second-axis direction parallel to a first plane orthogonal to the first-axis direction. The first magnetic field generator is movable in the second-axis direction with respect to the driver and the magnetic field sensor. The driver is spaced from and overlaps a part of the first magnetic field generator in the first-axis direction, and extends across the part of the first magnetic field generator in a third-axis direction parallel to the first plane and orthogonal to the second-axis direction. A center position of the magnetic field sensor in the third-axis direction is different from that of the first magnetic field generator.
