項に記載の磁気検出装置。[Claims for Utility Model Registration] (1) The test object and the magnetoresistive element are brought into contact with each other in a radial magnetic field in which the magnetic flux density is dense near the test object and coarse near the magnetoresistive element, and the pitch of the magnetoresistive element is adjusted. A magnetic detection device characterized in that the pitch is larger than 1/2 of the magnetic material pitch of the subject. (2) The radial magnetic field is formed by a magnet or a magnetic material, one of which faces facing each other in parallel is narrower than the other face.
The magnetic detection device described in section.
