Document Type and Number:
WIPO Patent Application WO/2011/148678
Kind Code:
A1
Abstract:
Provided is a LC co-sintered substrate which can be produced with a high degree of accuracy and which can prevent reduction of the inductance value of a coil. A LC co-sintered substrate (10) is provided with (a) a substrate main body (12) having magnetic layers (14a, 14b) composed of a magnetic ceramic material, and first and second dielectric layers (16a, 16b) which are laminated on both sides of the magnetic layers (14a, 14b) and which are composed of a dielectric ceramic material, (b) coils (20) formed on the inside of the magnetic layers (14a, 14b), and (c) a capacitor (22) formed on the inside of only the second dielectric layer (16b).
