Zusammenfassung:The present invention suppresses balancing filter insertion loss and reduces the size of a balancing filter. The balancing filter (100) according to one embodiment of the present invention is provided with: first through fifth terminals (P11)-(P15); a first inductor (L110), a second inductor (L113), and a third inductor (L116); and a low-pass filter (LP32). The first inductor (L110) is connected between the first terminal (P11) and a grounding point. The second inductor (L113) is connected between the second terminal (P12) and the third terminal (P13). The third inductor (L116) is connected between the fourth terminal (P14) and the fifth terminal (P15). The low-pass filter (LP32) is connected between the second terminal (P12) and one end of the second inductor (L113). The low-pass filter (LP32) is connected between the third terminal (P13) and the other end of the second inductor (L113).
