A thin-film magnetic head and a method of manufacturing the same are provided capable of achieving accurate control of a magnetic pole width and sufficient overwrite characteristics even with a reduced magnetic pole width. A first non-magnetic body and a second non-magnetic body are disposed on and under a flat surface including an upper surface or a lower surface of a write gap layer, respectively. The first non-magnetic body has a wedge-shaped cross section taken along a surface perpendicular to both of the flat surface and a track surface (air bearing surface), with a tip facing the track surface (air bearing surface) side. Since a photolithography process is performed on a gentle slope of the first non-magnetic body, effects of light reflected from an underlying layer can be reduced, whereby a product with excellent processing accuracy can be obtained. Further, the first and second non-magnetic bodies can suppress leakage of magnetic flux between the two magnetic layers facing each other with the write gap layer in between.
