<P>PROBLEM TO BE SOLVED: To provide an improved, compact and low loss laminated resonator. <P>SOLUTION: A laminated resonator 10 includes: a substrate 20 having a plurality of recessed portions formed on an upper surface; a first inductor lower electrode 32 disposed in one of the recessed portions and electrically connected to an input terminal electrode 12; first and second capacitor lower electrodes 35, 37 partly disposed in some of the recessed portions and electrically connected to a ground electrode 16; a second inductor lower electrode 38 disposed in one of the recessed portions and electrically connected to an output terminal electrode 14; a dielectric layer 24 formed on the substrate; a first upper electrode 48 formed on the dielectric layer so as to be electrically connected to the first inductor lower electrode and partly opposed to the first capacitor lower electrode; and a second upper electrode 50 formed on the dielectric layer so as to be electrically connected to the second inductor lower electrode and partly opposed to the second capacitor lower electrode. <P>COPYRIGHT: (C)2013,JPO&INPIT |
