PURPOSE: To make it possible to shift an operation point and to obtain a magnetic head dealing with a higher sensitivity and high frequency by inclining the magnetization direction of a magnetization fixing film by <30 deg. in a magnetization direction of a magnetization rotating layer from the direction of head depth. CONSTITUTION: A spin valve type MR element 100μm×5μm arranged with a high-coercive force layer 2 at its end is formed on a substrate 4 and is worked to a rectangular shape; thereafter, leads 3 consisting of Cu about 200nm are formed. In such a case, the magnetization direction (easy axis) of the magnetization rotating layer is inclined by executing the film formation in a bias magnetic field or a heat treatment which is executed at 200 to 300 deg.C in the magnetic field after the film formation or the element formation. The heat treatment is executed while the bias magnetic field is impressed with inclination by 20 deg. in the magnetization direction of an antiferromagnetic layer (FeMn), by which the magnetization direction (easy axis) is inclined.
