    摘要： The present invention aims to provide a magnetic head having an air bearing surface (ABS) composed of a worked surface being flat and smooth and having a reduced step produced between a rail portion on the ABS and an element portion. For achieving the object, the present invention makes a first predetermined depth deeper than a second predetermined depth in a manufacturing method of a magnetic head, which method executes the following steps. In the method, an electromagnetic transducing element is formed on a board, and then only the specific plane, which is opposed to a magnetic recording medium, of the board is removed up to a first predetermined depth. An insulating film, which is composed of the same material as that of an insulating layer used at the time of the formation of the element, is formed on the surface of the board after the removal and the surface of the element portion, and then the insulating film is polished by a chemical mechanical polishing method till the element is exposed. After that, a recessed portion having a second predetermined depth is formed on the insulating film.
