Lamination type coil component and method of producing the same

摘要

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 (6) having a thickness (T2) thinner than the thickness (T1) of the coil pattern is arranged so as to surround the coil pattern. Plural magnetic green sheets containing magnetic green sheets each having the coil pattern and the magnetic material layer formed thereon are laminated and press-bonded. Thus, a laminate is formed in which the thickness (T1 + T3 = Ta) of the electrode materials in the area where the via-hole is formed is thicker than the sum Tb of the thickness (T2) of the magnetic material layer and the thickness (T4) of the magnetic green sheet in the area surrounding the via-hole, and press-bonded.
