Abstract:
1. A high frequency electronic component comprising: a layered substrate including dielectric layers and conductor layers alternately stacked; a circuit for processing high frequency signals that is formed through the use of part of the conductor layers and located inside the layered substrate; a plurality of functional terminals for inputting and outputting signals relating to functions of the circuit; and a plurality of ground terminals connected to a ground, wherein: the conductor layers include a conductor layer for grounding located inside the layered substrate and connected to the ground; at least part of each of the functional terminals and at least part of each of the ground terminals are located on a bottom surface of the layered substrate; the high frequency electronic component further comprises a conductor section for grounding that is located on the bottom surface of the layered substrate and connected to the ground; and the conductor section for grounding includes: a center portion located in a region surrounded by the functional terminals and the ground terminals on the bottom surface of the layered substrate; and coupling portions for coupling the center portion to the ground terminals, and the conductor section for grounding is connected to the conductor layer for grounding via at least one through hole formed inside the layered substrate.
