Abstract
An electrode material for formation of a coil is applied in an area including a via-hole, whereby a coil pattern is formed with the electrode material being filled into the via-hole. A magnetic material layer having a thickness T that is less than the thickness T of the coil pattern is arranged so as to surround the coil pattern. A plurality of magnetic green sheets each having the coil pattern and the magnetic material layer provided thereon are laminated and press-bonded. Thus, a laminate is formed in which in the area where the via-hole is provided, the sum Ta of the thickness T of the electrode material in the via-hole and the thickness T of the coil pattern is greater than the sum Tb of the thickness T of the magnetic green sheet and the thickness T of the magnetic material layer.
