Abstract
A magnetoresistive head of the present invention is not easily damaged by electrostatic discharge, and is easy to manufacture. A magnetoresistance effect element is interposed between upper and lower shields composed of soft magnetic material through first and second gaps composed of an insulating material. The lower shield is connected to a slider via a slider protective film, which is an insulating substance. The magnetoresistive head is constructed so that a capacity Cg between the magnetoresistance effect element and the lower shield is 6.3 or more times a capacity between the lower shield and the slider by using a material (e.g., silicon carbide) exhibiting a large relative dielectric constant as, e.g., a second gap material.
