Abstract
An actuator device includes a drive assembly that is movable in a first direction, a sensor magnet that extends in the first direction that is a magnetization direction, the sensor magnet being fixed to the drive assembly, and a magnetic sensor that opposes the sensor magnet in a second direction intersecting the first direction to detect a magnetic flux of the sensor magnet. As viewed from the second direction, a width of the sensor magnet at a portion where a barycenter of the sensor magnet is positioned is wider than a width of two ends of the sensor magnet in the first direction.
