Interdigital transducers (IDT electrodes), reflectors, etc., are formed on a piezoelectric substrate. An unbalanced input/output terminal is connected to a first input/output terminal. A first inductor is connected between a first terminal, which is one of the balanced input/output terminals, and a second terminal, which is the other of the balanced input/output terminals. Further, a second inductor is connected between the first terminal in the balanced input/output terminals and a second input/output terminal, and the second terminal in the balanced input/output terminals is connected to a third input/output terminal.
