A composite type thin-film magnetic head. In one embodiment, a substrate is used as a base, and an insulating film, a lower shielding magnetic film, a magneto-resistive element, an upper shielding magnetic film, a magnetic gap film, a recording inductive magnetic film and a protective layer are laminated on this base. An inductive head used for recording is formed by the upper shielding magnetic film. A magnetic gap film, a recording inductive magnetic film, and a magneto-resistive head used for playback are formed by the magneto-resistive element. The upper shielding magnetic film and recording inductive magnetic film are formed by an electroplating of permalloy. The upper shielding magnetic film has a lower nickel concentration on the side of the magnetic gap film than on the side of the magneto-resistive element.
