Abstract:
An elastic wave device includes a piezoelectric substrate and an interdigital transducer (IDT) electrode. The IDT electrode is disposed on the piezoelectric substrate and includes an electrode layer including molybdenum as a main component. The duty ratio of the IDT electrode is about 0.3 to about 0.48.
