PROBLEM TO BE SOLVED : To provide a magnetoelectric transducer having a thin thickness and a small-sized magnetic sensor using the transducer. SOLUTION : This magnetoelectric transducer 20 is integrally constituted by adhering a soft magnetic board 5 formed with a magnetoresistance effect film 1 to a hard magnetic board 6 made of a rare earth element and the like for applying a bias magnetic field and laminating it. Thus, since the transducer 20 contains a hard magnetic material for applying the bias magnetic field and is integrated, the thickness can be reduced, and a small-sized magnetic sensor can be constituted.
