The method is capable of manufacturing a reliable magnetic head, in which an upper magnetic coil can be securely insulated from a coil and variation of coil resistance can be restrained. The method of manufacturing a magnetic head having a write-head comprises the steps of: forming a recording coil of the write-head formed in a workpiece; coating a surface of a coil forming area of the write-head, in which the recording coil is formed, other than a front end part of a lower magnetic pole of the write-head, with a protection layer, which prevents the recording coil from being etched by ion milling; and etching a pole end section of the write-head, by ion milling, so as to have a prescribed width.
