Title:
ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2013/099562
Kind Code:
A1
Abstract:
Provided is an electronic component wherein generation of spurious waves can be suppressed.
A laminated body (12) is configured by laminating a plurality of insulator layers (18). An LC parallel resonator (LC1) is provided in the laminated body (12) and configured of a coil (L1) and a capacitor (C1), and forms an annular shape in planar view from the x axis direction. The capacitor (C1) includes: a capacitor conductor layer (30a), which is connected to one end of the coil (L1); and a resonant ground conductor layer (34), which is connected to the other end of the coil (L1), and is provided further toward the positive direction side than the capacitor conductor layer (30a) in the z axis direction, said resonant ground conductor layer (34) facing the capacitor conductor layer (30a) with an insulator layer (18) therebetween. An external electrode (15) is provided further toward the negative direction side than the LC parallel resonator (LC1) in the z axis direction, and is facing the capacitor conductor layer (30a) with an insulator layer (18) therebetween.
