ABSTRACT:
Dielectric sheets 2 having internal electrodes 4 and 5 formed on the respective surfaces thereof, a dielectric sheet 2 having an outgoing electrode 6 formed on the surface thereof, and a dielectric sheet 2 having a shielded electrode 3 formed on the surface thereof are piled and integrally sintered to form a lamination. Grounding external electrodes are formed on first and second opposite sides of this lamination, respectively, and an input/output external electrode is formed on a third side thereof. An end portion 4a of the internal electrode 4 and an end portion 3a of the shielded electrode 3 are connected to the grounding external electrode on the first side. An end portion 5a of the internal electrode 5 and an end portion 3b of the shielded electrode 3 are connected to the grounding external electrode on the second opposite side. An end portion 6a of the outgoing electrode 6 is connected to the input/output external electrode on the third side. The end portion 6b of the outgoing electrode 6 is capacitance-coupled with the adjacent internal electrode 5.
