PROBLEM TO BE SOLVED: To provide a balance filter suitable for downsizing. SOLUTION: The balance filter is configured with: strip line resonators SL1a, SL1b for configuring a resonance electrode at an unbalanced side; strip line resonators SL2a, SL2b for configuring a resonance electrode of a balanced side provided adjacent and opposite to the unbalanced side strip line; strip line resonators SL3a, SL3b configuring a stage number configuration resonance electrode provided adjacent and opposite to the balanced side strip line; and an impedance element Z for coupling the balanced side resonance electrode with the stage number configuration resonance electrode.
