ABSTRACT:
A rotation angle detector detects a rotation angle of a magnetic field by selectively using a hall element from a plurality of hall elements disposed on one side of a semiconductor substrate. The hall elements are equiangularly disposed to each other in a ring shape. The rotation angle of the magnetic field is detected by using a portion of an output signal of the hall element having a substantially linear output characteristic.
