Abstract
An elastic wave device includes an IDT electrode on a piezoelectric substrate to define a longitudinally coupled resonator elastic wave filter, a three-dimensional wiring portion on the piezoelectric substrate and connected to the longitudinally coupled resonator elastic wave filter, and a cover surrounding the longitudinally coupled resonator elastic wave filter on the piezoelectric substrate. The three-dimensional wiring portion includes a lower layer wiring line, an upper layer wiring line, and an insulating layer stacked between the lower layer wiring line and the upper layer wiring line. The cover includes a portion on the three-dimensional wiring portion.
