| Zusammenfassung: | According to the present invention, a transmission filter (41) has a transmission filter circuit (10) and an additional circuit (30). The transmission filter circuit (10) forms a signal path (R1) thatconnects a terminal (P1) and a terminal (P2). The additional circuit (30) is connected to a node (N1) located on the signal path (R1) between the terminal (P1) and the transmission filter circuit (10), and a node (N2) located on the signal path (R1) between the terminal (P2) and the transmission filter circuit (10), and forms a signal path (R3) that connects the node (N1) and the node (N2). The additional circuit (30) has a resonator group (31), a capacitive element (32), and an inductance element (33) on the signal path (R3). The inductance element (33) is electromagnetically coupled to thetransmission filter circuit (10).
