Abstract:
An elastic wave device includes an interdigital transducer (IDT) electrode disposed on an upper surface of a piezoelectric substrate, a wiring electrode disposed on the upper surface of the piezoelectric substrate and connected to the IDT electrode, and a first insulator layer disposed on the upper surface of the piezoelectric substrate. The first insulator layer seals the IDT electrode and the wiring electrode and includes a first resin and a first filler. A resin layer including no filler is provided on an upper surface of the first insulator layer. An inductor electrode is disposed on an upper surface of the resin layer. A second insulator layer is disposed on the upper surface of the resin layer and covers the inductor electrode. A terminal electrode is disposed on an upper surface of the second insulator layer. A connecting electrode electrically connects the wiring electrode, the terminal electrode, and the inductor electrode.
