Claim 10:
11. A detection device comprising:
a main detection element configured to detect a physical quantity that changes according to a rotation of a detection target;
a sub detection element configured to detect a physical quantity that changes according to the rotation of the detection target;
a signal processing unit configured to output main rotation information that is information according to a detection value of the main detection element and sub rotation information that is information according to a detection value of the sub detection element; and
a package configured to seal the main detection element, the sub detection element, and the signal processing unit, wherein
centers of the main detection element and the sub detection element are arranged at positions displaced from a detection center of the detection target,
the main detection element is arranged at a position closer to the detection center than the sub detection element,
the package is arranged at a position where a center of the package deviates from the detection center,
the main detection element includes a first main detection element and a second main detection element,
the sub detection element includes a first sub detection element and a second sub detection element,
the first main detection element and the first sub detection element are mounted on one surface of a lead frame, and
the second main detection element and the second sub detection element are mounted on the other surface of the lead frame.
