Abstract
A hybrid filter device () includes an acoustic wave device (AD) that includes an acoustic wave resonator and a passive device (PD) that includes an inductor element or an inductor element and a capacitance element. At least one of the acoustic wave device (AD) and the passive device (PD) is mounted on a substrate () of the hybrid filter device () and the acoustic wave device (AD) and the passive device (PD) are electrically connected to each other. The acoustic wave device (AD) overlaps the passive device (PD) when the hybrid filter device () is viewed in a direction perpendicular to one main surface () of the substrate ().
