Abstract
An elastic wave device includes a first elastic wave resonator unit including a first IDT electrode and a second elastic wave resonator unit including a second IDT electrode and satisfies Wc<(Wa+Wb), where Wa is a dimension of a high acoustic velocity region on a first busbar side in a direction along which electrode fingers extend in the first IDT electrode, Wb is a dimension of a high acoustic velocity region on a fourth busbar side in the direction along which the electrode fingers extend in the second IDT electrode, and Wc is a dimension of an inter-stage connection portion.
