ABSTRACT:
A laminated ceramic electronic component includes a plurality of conductor pattern layers for a coil arranged to overlap each other to form substantially U-shaped conductors for the coil. The conductors for the coil are electrically connected in series through via holes for inner layer connection provided in ceramic green sheets to form a spiral coil. A plurality of leading conductor pattern layers also overlaps each other to form leading conductors. One leading conductor pattern layer is disposed per a predetermined number of conductor pattern layers for the coil. An end of each leading conductor pattern layer is in contact with the corresponding conductor pattern layer for the coil. In other words, the thickness of the lead conductors is less than the thickness of the conductors for the coil.
