Abstract

An elastic wave device includes a multilayer body, an antenna terminal, a ground terminal, a signal terminal, an IDT electrode, and an insulating film. The multilayer body includes a support substrate and a piezoelectric film disposed on the support substrate. The antenna terminal is disposed on or above the support substrate. The ground terminal is directly disposed on the support substrate. The signal terminal is disposed above the support substrate. The IDT electrode is disposed on the piezoelectric film. The insulating film is disposed between the support substrate and the signal terminal. The multilayer body includes one of a layer made of a high acoustic-velocity material and an acoustic reflection layer.
