| Zusammenfassung: | An acoustic wave device includes: a multilayer structure that has plural surfaces which principal surfaces of plural layers provide; a chip including an acoustic wave filter and mounted on a first surface; a resin unit sealing the chip; a wiring pattern that is formed on a second surface and electrically connected to at least one of resonators; a ground pattern that is formed on the second surface along a part of the wiring pattern, and is away from the wiring pattern; and an external terminal that is formed on a third surface and electrically connected to the wiring pattern and the ground pattern, the third surface being disposed on an opposite side of the first surface with respect to the second surface; wherein a part of the wiring pattern that comes closest to the ground pattern is substantially formed in parallel with the ground pattern. |
