Abstract
A Hall IC of an actuator calculates a relative angle by using magnetic flux densities in two directions, and corrects a linearity error in the relative angle by using correction values at correction points and a function to calculating an interpolated correction value between correction points, the correction values and the function being stored in a storage. The storage stores, as correction values at outermost correction points in a relative angle range, correction values Lα and Lβ causing linearity errors which are outermost ones of plural extremums to be equal to or less than linearity errors which are other ones of the plural extremums each of which is located inwardly next to the outermost extremum, the plural extremums being exhibited by the linearity error in the relative angle which is corrected by using an interpolated correction value calculated from the function which uses the correction values as parameters.
