    摘要： An acoustic wave device includes a main resonator and a sub resonator each having a substrate, a lower electrode provided on the substrate, a piezoelectric film provided on the lower electrode, and an upper electrode provided on an upper side of the piezoelectric film. The sub resonator has a mass addition film on the upper electrode in a resonance area in which the upper electrode and the lower electrode face each other. At least one of the main resonator and the sub resonator is provided with a frequency control film on an upper side of the resonance area, and the frequency control film has a weight per unit area smaller than a weight of the mass addition film per unit area.

    摘要： A filter device includes a filter element that has piezoelectric thin-film resonators arranged in series arms and parallel arms, and a package that houses the filter element in a face-down state. In this filter device, the filter element and the package are electrically connected to each other through bumps. The package includes first pad parts on which the bumps are placed, and transmission paths that electrically connect the first pad parts to the outside. The filter element includes second pad parts that are electrically connected to the first pad parts through the bumps, and wiring parts that electrically connect the second pads to the piezoelectric thin-film resonators and electrically connect the piezoelectric thin-film resonators to one another. In this structure, inductances formed with the transmission paths are connected in series to the piezoelectric thin-film resonators.
