Abstract: An MR element suppressing a false writing into a medium with an MR part has a CPP structure. The MR part includes a nonmagnetic intermediate layer and first and second ferromagnetic layers so as to interpose the nonmagnetic intermediate layer. First and second shield layers respectively have an inclining magnetization structure of which a magnetization is inclined with regard to a track width direction. The first and second ferromagnetic layers are respectively, magnetically coupled with the first and second shield layers. A magnetization direction adjustment layer for adjusting at least a magnetization direction of the first ferromagnetic layer is positioned at a rear end surface side of the first ferromagnetic layer, which is opposite to a front end surface receiving a magnetic field detected in the MR part.
