PROBLEM TO BE SOLVED: To attain a magnetic head equipped with a magneto-resistance effect element, which is miniaturized as desired without any variances in shape or size by allowing a core width to be made finer without complicating processes needlessly, corresponding to a higher recording density in the future. SOLUTION: By a CMP method, a first part A, a magnetic domain control film 8, and an insulating film 7 positioned on the MR element 10 of a second film 9 are polished to make a surface flat. More specifically, by using the second part B of the second film 9 as a polishing stopper, the first part A, the magnetic domain control film 8, and the insulating film 7 positioned on the MR element 10 of the second film 9 are polished once to continuously make the surface flat.
