One of a pair of comb electrodes of one of the two first IDTs is connected to one of the two balanced terminals, and one of a pair of comb electrodes of the other one of the two first IDTs being connected to the other one of the two balanced terminals. The other comb electrodes of the two first IDTs are connected in series, and one of a pair of comb electrodes that form an IDT that is included in the at least five IDTs and is not connected to the two first IDTs is grounded.

摘要： An acoustic wave element of the present disclosures has a piezoelectric substrate and an acoustic wave resonator on a main surface of the piezoelectric substrate. The acoustic wave resonator is one being divided into a first IDT electrode and a second IDT electrode which are electrically connected to the first IDT electrode. The first IDT electrode includes a first comb-shaped electrode on the signal input side and a second comb-shaped electrode on the signal output side. The second IDT electrode includes a third comb-shaped electrode on the signal input side and a fourth comb-shaped electrode on the signal output side. The direction of arrangement of the third comb-shaped electrode and the fourth comb-shaped electrode from the third comb-shaped electrode toward the fourth comb-shaped electrode is different from the direction of arrangement from the first comb-shaped electrode toward the second comb-shaped electrode.
