A branching filter suppresses the effect of a ripple at a high frequency side of a first band-pass filter having a relatively low frequency passband and achieves sufficient pass band widths of the first and second band-pass filters. The branching filter includes a first band-pass filter having a relatively low frequency passband and a second band-pass filter having a relatively high frequency passband. The first and second band-pass filters each have a SAW filter having a ladder circuit structure. The second band-pass filter has first to third parallel resonators. The first and second parallel resonators are commonly connected to a common-connection ground terminal. A first inductance is connected between the common-connection ground terminal and a ground potential. In the branching filter, a relationship f1>f0>f2 is satisfied, wherein f0 denotes an average of resonant frequencies of all the parallel resonators.
