Abstract
A magneto-resistive effect element is provided with a first soft magnetic layer, a magneto-resistive effect film formed directly on the first soft magnetic layer. and a second soft magnetic layer formed on the magneto-resistive effect film. The magneto-resistive effect element is configured as allowing electric current to flow in the thickness-wise direction. The first soft magnetic layer is composed of columnar crystals. The magneto-resistive effect film has an anti-ferromagnetic layer. The anti-ferromagnetic layer is formed directly on the first soft magnetic layer.
