    摘要: An acoustic wave filter having excellent steepness is provided without adding any exterior components or any new manufacturing steps. A plurality of filters (10-1) each having a first resonator (2a-1) placed in a serial arm and having a resonance frequency frs and an anti-resonance frequency fas, and a second resonator (4a-1) placed in a parallel arm and having a resonator frp and an anti-resonance frequency fap are provided on a same substrate, where the resonance frequency frs of the first resonator is higher than the resonance frequency frp of the second resonator; the anti-resonance frequency fas of the first resonator is higher than the anti-resonance frequency fap of the second resonator; and the filters (10-1) are connected in multiple stages. At least one of the filters (10-1) connected in multiple stages has a third resonator (6-1) having a resonance frequency frp and an anti-resonance frequency fap. The third resonator (6-1) is formed on the substrate and connected to the serial arm in parallel with respect to the first resonator (2a-1).
