A composite thin-film magnetic head includes a substrate; a first insulation layer laminated on the substrate; an MR read head element formed on the first insulation layer and provided with a lower shield layer, an upper shield layer and an MR layer in which a sense current flows in a direction perpendicular to a surface of the MR layer through the upper shield layer and the lower shield layer; a second insulation layer laminated on the MR read head element; an inductive write head element formed on the second insulation layer and provided with a lower magnetic pole layer, a recording gap layer, an upper magnetic pole layer whose end portion is opposed to an end portion of the lower magnetic pole layer through the recording gap layer and a write coil; and a nonmagnetic conductive layer electrically conducted with the lower shield layer and opposed to the substrate in order to increase substantially countered area between the lower shield layer and the substrate.
