A magnetic head is provided for further improving a correlation between
the dynamic characteristics and static characteristics. A lower magnetic
shield layer, a magneto-resistive layer, and an upper magnetic shield
layer are laminated on a base in this order. A lower lead layer and an
upper lead layer apply a sense current to the magneto-resistive layer in
a direction substantially perpendicular to the film plane thereof through
the magnetic shield layers. The lower magnetic shield layer and upper
magnetic shield layer have their shapes and sizes which substantially
exactly overlap each other, when viewed in a laminating direction. The
lower lead layer is electrically connected to the lower magnetic shield
layer. At least a portion of the lower lead layer closer to the lower
magnetic shield layer is made of a non-magnetic conductive material. The
upper lead layer is electrically connected to the upper magnetic shield
layer. At least a portion of the upper lead layer closer to the upper
magnetic shield layer is made of a non-magnetic conductive material.
