Abstract
An elastic wave device includes, on an elastic wave element substrate, an IDT electrode including electrode fingers, and reflectors. At least one electrode finger of each of the reflectors include a portion having a relatively large thickness in a longitudinal direction and a portion having a relatively small thickness in the longitudinal direction. The portion having the relatively large thickness each reflector is thicker than a thickness of the electrode fingers of the IDT electrode.
