摘要：
An acoustic wave device includes a plurality of serial resonators and a plurality of parallel resonators configured by acoustic wave elements, which plurality of serial resonators and plurality of parallel resonators configure a filter in which they are connected in a ladder configuration; a first capacitance part which is connected in parallel to at least one of the plurality of serial resonators; and a second capacitance part which is connected in series to at least one of the plurality of parallel resonators.
