Patent abstract
An angle sensor includes a magnet fixed to a rotational shaft and a Hall device disposed at neutral detection position C such that it faces the magnet, thereby detecting the rotational angle of the magnet based on an output of the Hall device. A magnetic member is attached to each of the magnetic poles of the magnet so that the maximum magnetic flux portions are away from the neutral detection position C in the circumferential direction of the shaft, thereby allowing the magnetic flux distribution to be biased to the direction opposite from the Hall device.
