According to an aspect of an embodiment, a method for producing a magnetic head includes forming a plating base layer on a substrate; forming a magnetic layer including an enlarged portion and a narrowed portion extending therefrom on the plating base layer by plating; forming a resist pattern on the magnetic layer and the plating base layer, the resist pattern corresponding to the shape of the magnetic layer and entirely covering the magnetic layer with a margin such that the margin around the narrowed portion is larger than that around the enlarged portion; and patterning the plating base layer by etching with the resist pattern used as a mask. The method further includes forming an insulating layer over the magnetic layer and the plating base layer; and forming an auxiliary magnetic layer on the insulating layer so that the auxiliary magnetic layer is magnetically connected to the magnetic layer.
