摘要:
A multilayer LC filter includes a terminal layer, and a plurality of capacitor electrode layers laminated together on the terminal layer. An inductor layer is disposed above the capacitor electrode layers to thereby form a laminated body. First and second strip-shaped side-surface electrodes are formed on opposite side surfaces of the laminated body, and are connected to input and output terminals of the terminal layer, respectively. The distal ends of the first and second strip-shaped side-surface electrodes extend to the corresponding side surfaces of the capacitor electrode layers, but do not reach the side surfaces of the inductor layer. Thus, the distances between the resonator inductors of the inductor layer and the strip-shaped side-surface electrodes are increased, and as a result, very little stray capacitance is generated between the resonator inductors and the side-surface electrodes.
