Abstract
A magnetoresistance effect element is provided with a magnetoresistance effect film (MR film) formed of alternative laminations of magnetic layers (for example, soft magnetic layers such as Fe--Ni--Co alloy layers) which are coupled anti-ferromagnetically with each other between adjacent magnetic layers and non-magnetic layers (for example, non-magnetic layers such as Cu layers) and provided with a bias soft magnetic layer (for example, SAL layer) for application of a bias magnetic filed to the magnetoresistance effect film, where the anisotropic magnetic field (Hk) in the plane of the bias medium layer is 5 Oe.ltoreq.Hk.ltoreq.15 Oe.
