A thin film magnetic head suitable for an increase in a packing density and an
increase in frequency of a magnetic recorder is provided, while the reliability
is maintained, and protrusion of a recording head portion from a surface facing
a magnetic disk due to thermal expansion is reduced. In the region between a joint
and a recording portion, the spacing dimension between the conductive layers of
a first coil adjacent to each other is allowed to be equal to the height dimension
of the conductive layer of the first coil, and the space of the first coil is filled
in with an inorganic material portion of an insulating layer. Regarding the perimeter
and the inside of the first coil, the portion which cannot be filled in with the
inorganic material portion of the insulating layer leaving no space is filled in
with an organic material portion, so that insulation is provided with reliability,
and thermal expansion of the insulating film due to the heat release from the first
coil is reduced by an inorganic material unlikely to thermally expand.
