A common mode filter (101) includes, between ports (P1, P2) and ports (P3, P4), a differential transmission line including a first signal line (SL1) and a second signal line (SL2). The first signal line (SL1) includes a first inductor (L1) arranged in series, and the second signal line (SL2) includes a second inductor (L2) arranged in series. In addition, a first resonant circuit (RC1) is provided between the first end of the first inductor (L1) and the ground, and a second resonant circuit (RC2) is provided between the first end of the second inductor (L2) and the ground. |
