To provide a rotation angle and torque detection device that is used for detection of a rotation angle or a rotation torque of, mainly, a vehicle steering wheel and accurately detects a rotation angle and torque in with a simple configuration.
The rotation angle and torque detection device includes control means 33 that outputs a rotation torque signal and a rotation angle signal and outputs at least one of a torque detection signal and an angle detection signal from at least one of a first magnetic detection element 28, a second magnetic detection element 31B and a third magnetic detection element 32B, so that, even in a case where a malfunction such as a failure happens in the control means 33, the malfunction can be detected by the torque detection signal or the angle detection signal from the first magnetic detection element 28, the second magnetic detection element 31B or the third magnetic detection element 32B. Thus, the rotation angle and torque detection device can be provided that accurately detects a rotation angle and a rotation torque with a simple configuration, especially with no sensor newly provided.
