Abstract
An elastic wave device that can be downsized. Certain examples of the elastic wave device include a substrate, an IDT electrode provided above the substrate, a wiring electrode provided above the substrate and connected to the IDT electrode, a sealing body sealing an excitation space in which the IDT electrode excites an elastic wave, and a sealing wall provided above the wiring electrode and forming a part of the sealing body. An outer periphery of the wiring electrode includes a protrusion. In one example, the wiring electrode includes a first wiring electrode provided on an upper surface of the substrate and a second wiring electrode provided on an upper surface of the first wiring electrode, an outer periphery of the second wiring electrode being provided with the protrusion.
