Provided are a branching filter capable of well branching two electrical signals having a wide frequency band, and a wireless communication module and wireless communication device using same. The branching filter is provided with an input terminal (11), a first output terminal (12a), a second output terminal (12b), a first line conductor (14a) which is electromagnetically coupled to a resonator (13a) of an input stage so as to interconnect the input terminal (11) and the first output terminal (12a), a capacitor (15a) which interconnects the first line conductor (14a) and ground, and a second line conductor (14b) which is electromagnetically coupled to a resonator (13b) of an output stage and is connected to the second output terminal (12b), wherein a low pass filter is configured from the first line conductor (14a) and the capacitor (15a), and a band pass filter is configured from the first line conductor (14a), the second line conductor (14b), and a plurality of resonators. The branching filter eliminates the need for a phase circuit and thus is capable of well branching two signals having a wide frequency band.
