Abstract
An attachment device is a device for attaching a physical quantity sensor to a measurement target. The attachment device includes a base on which the physical quantity sensor is mounted, a magnet having an attraction surface attracted to the measurement target, and an attraction yoke having attraction ends attracted to the measurement target by the magnetic force of the magnet. The attraction yoke is a yoke that is displaced relatively to the magnet in a first direction (a z direction) along a normal line of the attraction surface to attract at least a part of the attraction surface of the magnet and the attraction ends of the attraction yoke to the measurement target.
