Abstract
A rotational angle detector detects, with a detecting unit, a rotation of a rotary body rotating in cooperation with a steering wheel as a detection signal having a cyclic waveform that gradually increases or decreases in one cycle, calculates the detection signal as a rotational angle of the rotary body, and stores the detection signal. The rotational angle detector is used for detecting the rotational angle of a steering wheel of a car and allows the angle detection at a high solution in a simple structure.
