Document Type and Number:
WIPO Patent Application WO/2018/110054
Kind Code:
A1
Abstract:
To provide a structure in which an inductor and a capacitor are integrally formed in a single element, wherein the inductor has an excellent Q value. An LC device (10) comprises an element (20), an inductor (40), a capacitor (50), and a magnetic body (31). The element (20) is flat and is at least partially provided with an insulating resin layer. The inductor (40) has loop-shaped conductor patterns (401, 402) and is formed inside the element (20). The capacitor (50) is a mounted element and is arranged inside an opening in the loop-shaped conductor patterns (401, 402) within the element (20) with at least a mounting surface in contact with the resin layer. The magnetic body (31) forms part of the element (20) and is disposed between the conductor patterns (401, 402) and the capacitor (50) along substantially the entire length of the loop-shaped conductor patterns (401, 402).
