摘要:
A magnetic position detecting device includes a magnet; first to fourth magnetoelectric conversion elements formed on a virtual plane; and a flux guide made of a magnetic material. The flux guide includes first and second protrusions provided at a distance from each other in a direction parallel to the virtual plane. A specific portion recessed in a concave shape is provided in the flux guide in a mid-portion between the first and second protrusions. The first and fourth magnetoelectric conversion elements are provided approximately in the mid-portion between the first and second protrusions. The second magnetoelectric conversion element is provided between the first protrusion and the mid-portion.
