A magnetic head includes an upper magnetic pole layer formed by electroplating in which the density of the impressed current is increased in stages every predetermined period of time. The upper magnetic pole layer contains at least 60 mass % of Fe. The difference between the maximum Fe content and the minimum Fe content of the upper magnetic pole layer within 0.3 m from the interface with the gap layer is 6 mass % or less.
