First and second embodiments of thin-film magnetic heads each including a magnetoresistive element for reading out information as a result of moving relative to a magnetic recording medium. Each thin-film magnetic head includes a base, a lower shield layer that is formed on the base, a lower insulating layer, the magnetoresistive element, an upper insulating layer which is formed on the magnetoresistive element, and an upper shield layer. In order to make uniform the separation between each upper shield layer and its corresponding lower shield layer in the vicinity of its corresponding magnetoresistive element, a middle insulating layer is formed in the same film plane as its corresponding magnetoresistive element.
