Abstract:
A method of producing a lamination-type coil component comprising the steps of:applying an electrode material for formation of a coil to a magnetic green sheet having a via-hole provided therein into a desired pattern, wherein a coil pattern is formed with the electrode material being filled into the via-hole; forming a magnetic material layer having a thickness which is less than a thickness of the coil pattern such that the magnetic material layer surrounds the coil pattern; laminating a plurality of the magnetic green sheets each having the coil pattern and the magnetic material layer, wherein a laminate is formed, the laminate having a coil defined by said coil patterns formed on said plurality of magnetic green sheets formed therein; press-bonding the laminate, and heat-treating the press-bonded laminate to form a sintered body.
