Abstract
A method is provided for manufacturing a magnetic head for recording information on a magnetic recording medium in the form of a direction of magnetization, which enables manufacture of a magnetic head with gaps between turns of a conductive material constituting a coil being filled with an insulating material without any void and heat generation in the coil being suppressed. A photoresist with a higher flowability than an insulating material containing a metal element is applied to the coil. A part of the photoresist applied to the coil which covers the conductive material constituting the coil is removed by exposure and development, and on the conductive material, an insulating metal compound layer made of an insulating material containing a metal element and having a higher thermal conductivity than the photoresist is formed and polished for flattening.
