Abstract
A surface acoustic wave device includes a piezoelectric substrate, an IDT electrode, support layers, and a cover layer. A distance from a first end of a first partition-support layer to one of the outer-periphery-frame support layers closest to the first end is smaller than a distance from a second end of the first partition-support layer to one of the outer-periphery-frame support layers closest to the second end, and a distance from a first end of a second partition-support layer to one of the outer-periphery-frame support layers closest to the first end is larger than a distance from a second end of the second partition-support layer to one of the outer-periphery-frame support layers closest to the second end.
