ABSTRACT:
A surface acoustic wave device includes a piezoelectric substrate and an electrode section, disposed on the piezoelectric substrate, having a thin-film structure. The electrode section includes interdigital electrodes and junction electrodes connected to the interdigital electrodes. The interdigital electrodes each include corresponding first base layers containing Ta and Cu layers or Cu—M alloy layers each disposed on the corresponding first base layers, wherein M represents one or more elements selected from the group consisting of Ag, Sn, and C.
