Abstract
In a rotation angle detecting device, a signal from a first magnetism detecting element is outputted to a signal output part of a first IC package. A first signal output terminal outputs the signal from the first magnetism detecting element to outside. A signal from a second magnetism detecting element is outputted to a signal output part of a second IC package. A second signal output terminal outputs the signal from the second magnetism detecting element to outside. At least one of a power supply terminal and a ground terminal is located between the first and second signal output terminals. A rotary drive unit includes the device, a motor that rotates a detection object, and a motor power source wire. The ground terminal and a motor power source terminal are adjacent to each other.
