Abstract
An angle sensor includes a first magnetic sensor that outputs a first signal, a second magnetic sensor that outputs a second signal, and a processor that performs processing for generating an angle detection value. The processing for generating the angle detection value includes first processing for determining a first candidate value of the angle detection value, second processing for performing processing for determining an (n+1)th candidate value either once or more than once while incrementing n in value by one each time, the (n+1)th candidate value being determined by performing second computing processing using the first and second signals, first and second strengths, and an nth candidate value of the angle detection value, where n is an integer of 1 or more, and third processing for assuming the candidate value last determined by the second processing as the angle detection value.
