ANGLE SENSOR SYSTEM

A magnetic field generator generates a detection-target magnetic field related to an angle to be detected. An angle sensor includes a first and a second magnetic sensor and a processor. The first magnetic sensor detects, at a first detection position, a first applied magnetic field including the detection-target magnetic field, and generates first detection information having a correspondence with the angle to be detected. The second magnetic sensor detects, at a second detection position, a second applied magnetic field including the detection-target magnetic field, and generates second detection information having a correspondence with the angle to be detected. The processor generates an angle detection value by performing arithmetic processing using the first and second detection information. The ratio of a strength of the detection-target magnetic field at the second detection position to a strength of the detection-target magnetic field at the first detection position is 1.65 or more.
