Abstract: PROBLEM TO BE SOLVED: To obtain a magnetism detecting apparatus by which information on magnetism can be read out with high sensitivity from a magnetic medium whose residual magnetism is faint by a method wherein a magnet is attached to the intrusion side of the magnetic medium at a thin filmy magnetic sensor in such a way that the direction of a magnetic pole is at right angles to the advance direction of the magnetic medium, a return magnetic path is formed between the magnet and the magnetic sensor and a magnetic flux leakage is reduced. SOLUTION: A thin filmy magnetic sensor 1 is attached, by using a soft magnetic material 6, to the surface of the horizontal part 7a of a support base 7 which is formed in an H-shape. In addition, a permanent magnet 13 is attached to the intrusion side of a sheetlike magnetic medium 8 in such a way that the direction of a magnetic pole is at right angles to the advance direction of the magnetic medium 8. The permanent magnet 13 is constituted integrally in such a way that a U-shaped yoke 14 is assembled by the soft magnetic material 6 and that a spacer 15 is installed between the yoke 14 and the vertical part 7b of the support base 7, it is magnetically shielded by excluding a plane on which the magnet 13 faces the magnetic medium 8 so that a magnetic flux which is leaked to the side of the magnetic sensor 1 is reduced. Then, when the magnetic medium 8 is moved in parallel so as to come close to the magnetic sensor 1, an external-signal magnetic field 12 from the magnetic medium 8 is detected by the magnetic sensor 1 in a noncontact manner.
