Abstract:
A laminated LC filter, comprising:a laminated body including a plurality of insulation layers, a plurality of inductor patterns, and a plurality of capacitor patterns in a stacked arrangement; and at least three LC resonators having a plurality of inductors defined by said plurality of inductor patterns, and a plurality of capacitors defined by said plurality of capacitor patterns, said plurality of capacitors arranged such that said capacitor patterns are disposed opposite to said inductor patterns inside of said laminated body; wherein a filter having at least three stages is defined by at least three of said LC resonators connected to each other, the pattern widths of the inductor patterns of the LC resonators disposed at locations between both end portions of one of the plurality of insulation layers are wider than the pattern widths of the inductor patterns of the LC resonators located at both end portions of said one of the plurality of insulation layers.
