ABSTRACT:
A laminated coil component includes a coil conductor including a plurality of strip electrodes and via-holes inside an approximately rectangular ceramic laminate. The via-holes connect the ends of the strip electrodes. The axis of the coil conductor corresponds with the width direction Z of the ceramic laminate that is substantially perpendicular to both the laminated direction (thickness direction) X and the longitudinal direction Y of the ceramic laminate. The manufacturing process includes the steps of laminating ceramic green sheets having the strip electrodes and/or the via-holes and the ceramic green sheets having printed conductive patterns constituting external electrodes, and press-bonding and firing them.
