Abstract
A multiplexer includes a filter on a first path connecting a common terminal and an input/output terminal, and a second filter on a second path connecting the common terminal and a second terminal, the second filter having a passband that overlaps a generation frequency of Rayleigh wave ripples in the filter. The filter includes series arm resonators on the first path and a parallel arm resonator, the series arm resonators and the parallel arm resonator utilize an SH wave as a main mode, and a number of electrode finger pairs of the series arm resonator is fewest among numbers of electrode finger pairs of the series arm resonators.
