摘要： An electronic component capable of obtaining a large inductance value and a high Q value and a method of manufacturing the electronic component are provided. A coil includes a plurality of coil conductors incorporated in a multilayer structure, a plurality of lands provided at the plurality of coil conductors, and a via-hole conductor connecting the plurality of lands. Lead-out conductors are incorporated in the multilayer structure and connect the coil and external electrodes. The plurality of coil conductors form a substantially rectangular loop path in plan view from the z-axis direction by overlapping each other. The plurality of lands protrude toward outside the path at a short side of the path and do not overlap the lead-out conductors in plan view from the z-axis direction.

摘要： 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.

摘要： 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.

摘要： 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. A desired conductor and a structure within a sintered ceramic body are produced with high accuracy, and the manufacturing process is greatly simplified, and costs of the laminated ceramic electronic component are greatly reduced.

The inductances L and L', and the stray capacitances C and C' fulfill the conditions: LC>L'C', to thereby increase the high-frequency characteristics and the insertion loss in a high frequency area of the LC composite device.
