<p>Provided is an acoustic wave device with superior out-of-band attenuation characteristics. The acoustic wave chip (40) comprises at least two ground terminals (2d, 2e). The at least two ground terminals (2d, 2e) are disposed on a piezoelectric substrate (41). The at least two ground terminals (2d, 2e) are connected to a common connection point (23). The at least two ground terminals (2d, 2e) are adjacently disposed along one edge (41A) of the piezoelectric substrate (41). The common connection point (23) is disposed on a first electrode layer (33). The inductor (L2) is configured by at least one second electrode layer (34) and a connection electrode (39).</p> |
