ABSTRACT:
A position detector having a movable permanent magnet (5), a circuit board (6) having a magnetic sensor element (1) for detecting the movement of the permanent magnet and a molded resin case (2) supporting the circuit board. The circuit board (6) is surrounded by a box-shaped radiation shield (12) for shielding the circuit board against external electromagnetic radiation. The radiation shield is insert-molded in the mold resin case as its integral part. The radiation shield (12) includes a shield main body (12a) having an open end and a shield cover (12b) closing the open end of the shield main body. The molded resin case (2) has a cavity (2a) open on the same side as the open end of the shield main body (12a) and a case cover (2b) attached to the case opening for closing the cavity.
