Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a seat position sensor with high yield using a wide magnetoelectric transducer which can minimize the effects of leaked magnetic flux with a bias magnet and ensure the switching of the magnetoelectric transducer by controlling the magnetic flux density. SOLUTION: A box 1, a magnetoelectric transducer 4 switching the output at a specific magnetic intensity and a magnet 7 held by the box at the position facing the magnetoelectro transducer are provided. A shield plate 14 can go in and out of a gap 1d formed between the magnetoelectric transducer 4 and the magnet 7. On the other side of the magnet 7 over the transducer 4, a reverse bias magnet 6 applying a magnetic field in the opposite direction to the magnet 7 is provided in the constitution.
