Abstract

A rotation angle detection device includes: a detection portion that detects detection angle that univocally corresponds to rotation angle of a rotating body which is within a predetermined range, wherein the detection angle linearly increases from a minimum value to a maximum value as the rotation angle increases within a unit range, and the detection angle changes from the maximum value to the minimum value or from the minimum value to the maximum value at a boundary between unit ranges that are adjacent to each other; and a correction portion that corrects the detection angle so that the detection angle detected in the predetermined range has linear characteristics, if the boundary between the unit ranges is contained in the predetermined range.
