By forming a rearmost second coil piece so as to have a larger width in the track-width direction and a larger area than those of coil pieces, heat generated in a thin-film magnetic head can be effectively released to the rearmost coil piece. Thus, a temperature rise in the thin-film magnetic recording head can be further reduced than is possible today, thereby preventing the thin-film magnetic head from protrusion due to its thermal expansion.
