Abstract: A non-contact type position sensor enhanced in characteristics. A first magnetic element has a first magnetic detecting part at one end side thereof. A first magnet has one pole thereof fixed to the other side of the first magnetic element. A second magnetic element is positioned underneath the first magnetic element, and has a second magnetic detecting part at one end side thereof, and has the other pole of the first magnet at the other end side thereof. A third magnetic element is positioned substantially on circles concentric with the first magnetic element, and has a third magnetic detecting part at the one end side thereof. A second magnet has one pole fixed to the other end side of the third magnetic element. A fourth magnetic element is positioned underneath the third magnetic element, and has a fourth magnetic detecting part at one end side thereof, and also has the other pole of the second magnet at the other end side thereof.
