Abstract: PURPOSE:To detect a position of a magnet set to an internal object coated with a non-magnetic body by arranging a plurality of magnetic field detection sensors on a line in a direction orthogonal to a direction connecting N and S poles of the permanent, magnet set to the object, setting a direction in which a magnetic field is to be detected by the sensors to agree with the linear arranging direction of the sensors, and detecting tone magnetic field. CONSTITUTION:A plurality of magnetic field detection sensors 1, e.g. Hall elements are arranged on a line in a direction orthogonal to a direction connecting N and S poles of a permanent magnet, 2. The NS polar direction of the magnet, 2 is set as a Y axis, and the arranging direction of the elements 1 is set as an X axis. The elements 1 are directed in a direction to detect an X-axis component Bx of a magnetic field. A driving current for the elements 1 is supplied to a Z axis at right angles to the X axis. A voltage induced in a Y-axis direction perpendicular to the Z axis is proportional to the X-axis component of the magnetic field. In other words, the magnetic field to be detected by the elements 1 is positioned in the X-axis direction. An output voltage of the elements 1 is amplified, A/D converted and corrected, whereby a value of the magnetic field is obtained. The value is interpolated on the line and a distribution of the Bx on the line is obtained. A moving amount of an object is detected from a relation between an X coordinate value of a point where the Bx becomes zero and an X coordinate value of the magnet 2.
