Abstract
An acoustic wave device includes: a piezoelectric thin film resonator that is connected between a first node and a second node; and a resonant circuit that is connected in parallel with the piezoelectric thin film resonator between the first node and the second node, and has a resonant frequency fthat meets a condition of 2×fa×0.92≤fwhere fa represents an antiresonant frequency of the piezoelectric thin film resonator.
