Abstract
A thin-film magnetic head which can locally project a reproduction element toward a recording medium and a method of manufacturing the thin-film magnetic head are provided. The thin-film magnetic head includes a reproduction element, a recording element which is stacked on the reproduction element and has a pair of magnetic core layers and a coil layer configured to apply a recording magnetic field to the magnetic core layers, and a heat-emitting member emitting heat by electrification, which causes the reproduction element to project toward the recording medium by thermal expansion. The heat-emitting member is disposed below the coil layer.
