Patent ID: 8754723

Claim:
An electronic component comprising: a laminate including a plurality of laminated insulating material layers; a main line provided within the laminate; a sub-line provided within the laminate and electromagnetically coupled to the main line to define a directional coupler; first and second external electrodes provided on a bottom surface of the laminate and connected to both ends of the main line, respectively; third and fourth external electrodes provided on the bottom surface of the laminate and connected to both ends of the sub-line, respectively; and a warpage prevention conductor provided on one of the plurality of insulating material layers that is located on a top surface side of the laminate with respect to one of the plurality of insulating material layers on which the main line is provided and with respect to one of the plurality of insulating material layers on which the sub-line is provided, the warpage prevention conductor overlapping with the first to fourth external electrodes when seen from a lamination direction in a plan view; wherein a conductor layer that is not connected to any of the main line and the sub-line is not provided on one of the plurality of insulating material layers provided on a bottom surface side of the laminate with respect to the one of the plurality of insulating material layers on which the warpage prevention conductor is provided; and the warpage prevention conductor is not electrically connected to any other conductor within the laminate.
