Abstract
An acoustic wave device includes a common terminal, a first terminal, a second terminal, a first filter, a second filter, and an inductor. The first filter has a pass band corresponding to a relatively low frequency range and includes a surface acoustic wave filter using an SH wave. The second filter has a pass band corresponding to a relatively high frequency range. The first filter is between a branch point and the first terminal on a path connecting the common terminal and the first terminal. The second filter is between the branch point and the second terminal on a path connecting the common terminal and the second terminal. The inductor is on a path connecting the branch point and the first filter.
