Abstract
An elastic wave device includes a piezoelectric substrate including first and second primary surfaces opposing one another, a via electrode extending through the piezoelectric substrate, and a wiring electrode on the first primary surface of the piezoelectric substrate. The via electrode is connected at one end to the wiring electrode, and the via electrode includes a locking section at the one end, on the wiring electrode side. The locking section extends on the first primary surface of the piezoelectric substrate.
