Acoustic wave device

An acoustic wave device comprising:

• a support including a support substrate with a thickness direction in a first direction;
• a piezoelectric layer provided on the support;
• and
• a plurality of resonators each including a functional electrode provided to the piezoelectric layer;
• wherein the support is provided with a hollow portion at a position overlapping at least a portion of each of the plurality of resonators in plan view in the first direction;
• the plurality of resonators include a first resonator and a second resonator adjacent to each other;
• each of the functional electrodes includes one or more first electrode fingers and one or more second electrode fingers that overlap one another when viewed in a third direction;
• a through hole is provided to the piezoelectric layer between the first resonator and the second resonator;
• and
• the through hole is closer to the second resonator than to the first resonator in the third direction.
