Abstract
An acoustic wave device includes series resonators and parallel resonators formed on a main surface of a piezoelectric layer. The series resonators includes a first series resonator including first, second and third series-divided resonators and a second series resonator including fourth, fifth and sixth series-divided resonators. One of the first, second and third series-divided resonators which is disposed at a position where an electric signal is input first, has a first anti-resonance frequency. The others of the first, second and third series-divided resonators have a second anti-resonance frequency. One of the fourth, fifth and sixth series-divided resonators which is centrally disposed has the second anti-resonance frequency, the others of the fourth, fifth, and sixth series-divided resonators have the first anti-resonance frequency.
