ABSTRACT:
A rotation detecting apparatus capable of increasing the angle detecting precision without being affected by an offset signal resulting from a stress in a silicon chip. The rotation detecting apparatus includes a magnetic sensor array and a magnet rotatable in face-to-face relation with the magnetic sensor array. The magnetic sensor array includes a plurality of groups of sensor elements, each group including four sensor elements. The four sensor elements of each combined sensor element group are so arranged as to be oriented vertically and horizontally in four directions and connected parallel to each other.
