Abstract

An elastic wave apparatus includes first and second bandpass filters and the first bandpass filter is a ladder elastic wave filter. The mounting substrate includes an inductor which is connected between at least one of parallel arm resonators and a ground potential, a signal wiring at a hot side, which is connected to the first bandpass filter, and a ground wiring. When the mounting substrate is viewed from a side of a surface on which the elastic wave filter chip is mounted, a portion of the inductor overlaps with a portion of the signal wiring and a slit defining a wiring missing portion in which the ground wiring is absent in the ground wiring is provided in the overlapped portion.
