Abstract: A passive component (10A) comprising one input electrode layer (48) constituting an input terminal, one output electrode layer (50) constituting an output terminal, and four shield electrode layers (52a-52d) constituting shield terminals, all formed in the lowermost dielectric layer (S7) by via holes. The input electrode layer (48) is connected electrically with an input-side resonance electrode (26), in the vicinity of the second side face (14b) of a dielectric substrate (14), through a via hole (54) made in the fourth through sixth dielectric layers (S4-S6) and an input tap electrode (30). The output electrode layer (50) is connected electrically with an output-side resonance electrode (28), in the vicinity of the third side face (14c) of the dielectric substrate (14), through a via hole (56) made in the fourth through sixth dielectric layers (S4-S6) and an output tap electrode (32).

Abstract: A dielectric substrate (12) includes a filter unit (20), a non-balance/balance conversion unit (22), and a connection unit (24) for electrically connecting the filter unit (20) to the non-balance/balance conversion unit (22) which are formed in the dielectric substrate (12). A first resonator (26) has an electrode (36) formed on the main surface of a fourth dielectric layer (S4) and a via hole (38) penetrating through a first to a third dielectric layers (S1 to S3) and connecting the electrode (36) to a grounding electrode (18). A second resonator (28) has an electrode (42) formed on the main surface of the fourth dielectric layer (S4) and a via hole (44) penetrating through the first to the third dielectric layers (S1 to S3) and connecting the electrode (42) to the grounding electrode (18).
