PURPOSE:To form easily a magnetic pole projecting part in the vicinity of the medium facing tip part of a lower magnetic pole layer by adhering to the lower magnetic pole layer forming area on a substrate a magnetic layer having a projecting part in such a way that it gets over a mask from a mask pattern with the use of the mask pattern and then adhering the lower magnetic layer to the magnetic layer. CONSTITUTION:A resist mask pattern film 33 for forming the magnetic pole projecting part is formed on a plating base conductive film 32. After the magnetic layer 34 having the projecting part 34a in such a way that it gets over the film thickness of the mask pattern film 33 from the exposing base conductive film 32 is formed by plating, the mask pattern film 33 and its lower base conductive film 32 are removed, and a nonmagnetic insulating layer 35 is adhered and formed. The wrapping flat processing is executed, and a plating base conductive film 36 is adhered and formed on the surface, after which a resist pattern film 37 is formed. After respective layers are sequentially adhered and formed on a lower magnetic pole layer 38, they are cut along a cutting line B so that said tip surfaces of said layer 38 and the upper magnetic pole layer 43 can expose, and the medium facing surface is formed, whereby a thin film magnetic head with its magnetic pole projecting part 34a in the vicinity of the medium facing tip of the lower magnetic pole layer can be obtained. |
