Abstract
The branching filter has the piezoelectric substrate having the main surface on which there are formed a transmission filter, which includes an input electrode and an antenna electrode, and a reception filter, which includes an output electrodes and the antenna electrode. The branching filter also has the mounting substrate having, on a first main surface, a first electrode group that is connected to the transmission filter and reception filter and that is formed symmetrical with respect to a line when viewed from the above, and also having, on a second main surface locating on the opposite side to the first main surface, a second electrode group that is connected to the circuit interconnects of an external circuit board and that is formed symmetrical with respect to a line when viewed from the above.
