Patent ID: 7375977

Claim:
A multilayered electronic component comprising: a plurality of first ceramic layers that are laminated on each other in an integral manner to form a laminate; a second ceramic layer that is inserted and arranged at a desired position within the laminate; a coil wiring pattern defining a portion of a coil conductor, said coil wiring pattern being provided on the surface of each of said first ceramic layers; an external extension electrode connection pattern provided on a surface portion of said second ceramic layer; a coil connection electrode arranged so as to pass through a surface portion of said second ceramic layer that opposes an end portion of said coil wiring pattern with said second ceramic layer or said first ceramic layer disposed in between; a connection wiring pattern that is provided on the surface of said second ceramic layer and that connects together said external extension electrode connection pattern and said coil connection electrode; a first electrical conductor arranged on said first ceramic layer so as to extend therethrough in the thickness direction thereof and arranged to allow the end portions of said coil wiring patterns that oppose each of said first ceramic layer disposed in between to be electrically connected to each other and arranged to allow the coil wiring patterns to define said coil conductor; and a second electrical conductor arranged on said second ceramic layer or said first ceramic layer that is in contact with said second ceramic layer so as to extend therethrough in the thickness direction thereof and to electrically connect the end portion of said coil wiring pattern and said coil connection electrode which are opposed to each other; wherein the end portion of said coil wiring pattern that opposes the coil connection electrode is displaced on the surface of said first ceramic layer due to an increase or decrease in the number of said first ceramic layers; said coil connection electrode has a configuration in which a surface portion of said second ceramic layer opposed to said first ceramic layer or said second layer disposed in between is connected to the end portion of said coil wiring pattern that opposes the coil connection electrode, which is displaced due to an increase or decrease in the number of said first ceramic layers; and said connection wiring pattern has a configuration in which one portion of said coil connection electrode and one portion of said external extension electrode connection pattern are connected to each other.
