Angular position detecting apparatus for linearly detecting angular position in a wider range

An angular position detecting apparatus comprising:

• plural magnetic detecting elements for outputting an output signal in response to a rotation of a target detection object, each of the magnetic detecting elements having a range of an angular position in which an output characteristic becomes linear, the range being different from each other with respect to every magnetic detecting element;
• an output selector for selectively outputting outputs of a particular magnetic detecting element in a linear region, depending on the angular position;
• and
• an output adjustor for adjusting at least one of an amount of offset and an amplification factor regarding the outputs of the magnetic detecting elements, so that the outputs of the magnetic detecting elements are connected as a straight line.
