Abstract
A sensor core used in a non-contact type rotational angle sensor is constructed of an outer core made of a magnetic material, an inner core made of a magnetic material in a disc shape disposed coaxially with and inside the outer core, a first air gap produced between an inner peripheral surface of the outer core and an outer peripheral plane of the inner core, a second air gap produced extending in a radial direction of the outer core to the first air gap, and a plate-like magnet magnetized in its thickness direction and mounted in a mounting gap of the inner core. The inner peripheral surface of the outer core is provided with stepped portions so that the first air gap stepwise increases in dimension with approach toward the second air gap.
