A highly reliable magnetic head is provided where fluctuation in the form of the upper magnetic pole is prevented and recording density is improved. The magnetic head is equipped with a recording head where a lower tip magnetic pole (20a) and an upper tip magnetic pole (50a) are formed facing one another on both sides of a write gap (11) and a coil (22) is disposed on a rear side of the lower magnetic pole (20). The lower tip magnetic pole (20a) is provided with an apex part (20b) by forming the surface on the rear side on which the coil (22) is disposed as an inclined surface, and an insulating layer (26) that covers the coil (22) is formed to the rear of the lower tip magnetic pole (20a). The upper surface of the lower tip magnetic pole (20a) and the upper surface of the insulating layer (26) are formed as flat surfaces that are flush and a flat planarized upper magnetic pole (50) is provided on the other side of the write gap. |
