A thin-film magnetic head has a lower core layer, an upper core layer, a track width defining portion, and a first coil layer. The first coil layer has a spiral conductive pattern with a predetermined number of turns. The track width defining portion includes a gap layer and at least one of optional upper and lower magnetic pole layers. The first coil layer is provided behind the track width defining portion in the height direction. The upper face of the first coil layer is aligned in a reference plane defined by the interface between the track width defining portion and the upper core layer. The thin-film magnetic head has a decreased magnetic path length and exhibits decreased inductance.
