The invention is directed to improvement of a write element of a thin film magnetic head. In the write element, a first coil and a second coil are provided on a first insulating film formed on one surface of a first magnetic film and surround in a spiral form a back gap portion. A second yoke portion in the upper position comprises a wide portion, a narrow portion and a sloping flare portion. The wide portion has a flat surface and is connected to the first magnetic film by a back gap portion at the rear of the medium-facing surface. The narrow portion forms the second pole portion and the surface of the narrow portion being at a lower position than the surface of the wide portion. The sloping flare portion extends from the narrow portion to the wide portion, gradually increasing in width and its surface sloping upward away from the surface of the narrow portion to the surface of the wide portion.
