ABSTRACT:
An MR element includes a magnetoresistive film, a first magnetic shield film and a second magnetic shield film. The MR film includes at least one magnetic field response film, which responds to an external magnetic field. The first magnetic shield film and the second magnetic shield film are positioned at the two sides of the MR film. The first magnetic shield film includes a magnetic film, whose saturation magnetization is lower than the saturation magnetization of the magnetic field response film. The magnetic film occupies a position that is close to the magnetic field response film.
