PROBLEM TO BE SOLVED: To provide an elastic wave device which can fully obtain the attenuation amount outside a pass band.SOLUTION: The elastic wave device has: an element substrate 1; a plurality of elastic wave resonators S1-S4, P1-P2 which are formed on the element substrate; an input pad T1 which is formed on the element substrate, connected to at least one of the elastic wave resonators, and to which an electrical signal is inputted; an output pad T2 which is formed on the element substrate, connected to at least one of the elastic wave resonators, and from which the electrical signal is outputted; a seal ring SR which is formed on the element substrate and formed so as to surround the elastic wave resonators; and a first inductor which is formed between the seal ring and a ground. |
