PROBLEM TO BE SOLVED: To provide a magnetic head by which recording density of a medium in which information is recorded magnetically can be improved. SOLUTION: The magnetic head is provided with a magneto-resistance effect element having a first magnetization free layer having a ferromagnetic film, a first magnetization fixed layer having the ferromagnetic film in which the magnetization direction is fixed, a first spin valve layer having a first non-magnetic intermediate layer provided between the first magnetization free layer and the first magnetization fixed layer, a bias layer having a magnetic layer for applying a bias magnetic field of the track width direction being orthogonal to the track direction for the first magnetization free layer and a second magnetization free layer, a second magnetization free layer having the ferromagnetic film, a second magnetization fixed layer having the ferromagnetic film in which the magnetization direction is fixed, a second spin valve layer having a second non-magnetic intermediate layer provided between the second magnetization free layer and the second magnetization fixed layer, and a pair of electrodes for making a current of the direction being almost in parallel to the track direction for the magneto-resistance effect element to flow.
