Abstract

PURPOSE: To fix the width of a gap precisely within a fixed size by forming another layer after flattening a formed layer on each formation of respective layers at a winding part and magnetic circuit part.
CONSTITUTION: The patterning of a magnetic layer is performed by a thin film of Al, etc., easy to pattern and excellent in airtightness, only a part where a magnetic layer is formed is etched, and lift-off flattening is done by filling up the formed concave part with the magnetic layer. As for the formation of a pattern of the conductor layer of a coil, flattening is done by spin-coating after lift-off from an insulating film or conductor patterning. In a process where the conductor layer is made into an insulated layer, a temporarily dummy conductor layer is formed and after a temporarily dummy conductor is removed and substituted with a magnetic film, the magnetic film is stacked. As a result, unevenness is made in gap formation even if several layers are stacked. Therefore, rectangular gap 25 of gap width Wt less than a fixed size is formed on tape opposite surface 26 of magnetic layer 23 of substrate 21.
