PROBLEM TO BE SOLVED: To provide a branching filter in which wiring is facilitated and a reception fault hardly occurs, and which improves reliability and is easily installed. SOLUTION: A branching filter 1 comprises: a first filter 5 which fetches a signal supplied from an input terminal 2 via a capacitor C1 and selectively passes an input signal of a first frequency band (10-770MHz) set in advance; a distribution circuit 10 for branching the signal passed through the first filter 5 into two signals and supplying them to output terminals 12, 13; a second filter 15 which fetches a signal supplied from the input terminal 2 via a capacitor C6, selectively passes a signal of a second frequency band (1000MHz-2660MHz) set in advance and supplies the signal to an output terminal 14; and a third filter 25 which is connected between the input terminal 2 and the output terminal 14 and selectively passes a signal of a third (DC) frequency band set in advance.
