Abstract
An acoustic wave device includes a piezoelectric substrate, comb-shaped electrodes, wires, a sealing body, terminal electrodes, and connection electrodes. The comb-shaped electrodes are disposed on the piezoelectric substrate and are connected to the wires. The sealing body is disposed on the piezoelectric substrate in such a manner that the comb-shaped electrodes are sealed between the piezoelectric substrate and the sealing body. The terminal electrodes are disposed on the sealing body. The connection electrodes penetrate the sealing body so as to electrically connect the wires and the terminal electrodes, respectively. A first linear expansion coefficient in a first temperature range below a first glass transition temperature of the sealing body is larger than a second linear expansion coefficient in a second temperature range above the first glass transition temperature.
