Surface acoustic wave device and method for manufacturing the same

摘要

A surface acoustic wave device includes a piezoelectric substrate, an interdigital transducer (IDT) electrode, and a connecting portion that is electrically connected with the IDT electrode. The surface acoustic wave device further includes a wiring portion, a portion of which is disposed on the connecting portion, and a bump disposed on the wiring portion. The connecting portion includes a comb-shaped portion at an end of the connecting portion on which the wiring portion is disposed.
