In a thin-film magnetic head having a multilayered film developing a magnetoresistive effect, which is present between an upper shielding layer and a lower shielding layer both formed above an AlTiC substrate, a recess for defining the lower shielding layer is formed in an underlayer present on a surface of the AlTiC substrate, and a lower shielding layer made of NiFe is provided in the recess. A SiO<SUB>2 </SUB>film is interposed between the underlayer and the lower shielding layer.
