Abstract: A laminate-type electronic component includes has a first coil and a second coil, and the number of turns of the first coil is smaller than that of the second coil due to a positional relationship between input-output electrodes. As a result, the thickness of an outer layer on the first coil side is increased, that is, the magnetic path cross-sectional area of the outer layer is increased. Thus, the inductance of the first coil is decreased. The thickness of the outer layer on the second coil side is decreased, that is, the magnetic path cross-sectional area of the outer layer on the second coil side is decreased. Thus, the inductance of the second coil is decreased.

The manufacturing method for the laminated ceramic electronic component includes a process in which a green sheet including the inner electrode paste layer and the ceramic paste layer, is provided on a carrier sheet such that the inner electrode paste layer penetrates the green sheet from the top surface to the bottom surface thereof, and a process, in which laminates of the green sheet and the carrier film are adhered by pressing, and thereafter the carrier film is peeled off, are repeated to obtain the ceramic laminate, and the ceramic laminate is fired after pressing in the direction of the thickness to obtain the ceramic sintered body.

Abstract: A common-mode choke coil includes first to third spiral coils, in which the diameters of coil portions are substantially the same and the axes of the coil portions are aligned collinearly. Extended portions of the first and second coils have a flectional pattern and connect coil portions located at substantially the center in the longitudinal direction of sheets and input/output electrodes. The junctions of the extended portions and the coil portions have a folded configuration. Accordingly, the number of turns and the line length of the first coil are the same as those of the second coil.

Abstract: In a laminated impedance device, coil conductor patterns are electrically connected in series through via-holes to form a substantially U-shaped spiral coil. A first group of the coil conductor patterns defines a first coil portion of a high-permeability coil unit. A second group of the coil conductor patterns defines a second coil portion of a low-permeability coil unit, and a third group of the coil conductor patterns defines a third coil portion of the low-permeability coil unit. A fourth group of the coil conductor patterns defines a fourth coil portion of the high-permeability coil unit. The first, second and third coil portions are wound clockwise, while the fourth coil portion is wound counterclockwise, as viewed from the top of the impedance device. Therefore, the laminated impedance device yields a high inductance in the low-permeability coil unit, and can be mounted in any direction and orientation.

Abstract: In a method for manufacturing a laminated ceramic electronic component, a first transfer member and a second transfer member are prepared on a lamination stage to produce the laminated ceramic electronic component. The first transfer member includes a conductor-attached composite green sheet having a conductor on a portion of the surface thereof, including a non-magnetic ceramic region and a magnetic ceramic region, and a first carrier film that carries the conductor-attached composite green sheet. The second transfer member includes a ceramic green sheet and a carrier film that carries the ceramic green sheet. The laminated ceramic electronic component is thus produced through a first transfer step in which the ceramic green sheets are successively transferred, through a second transfer step in which the conductor-attached composite green sheet is transferred, and through a third transfer step in which the ceramic green sheet of the second transfer member is transferred.
