Abstract
A multiplexer () includes: a filter (L) that is arranged between a common terminal () and an input/output terminal () and that has a first pass band; a filter (H) that is arranged between the common terminal () and an input/output terminal (), that is formed of at least one acoustic wave resonator, and that has a second pass band located at a higher frequency than the first pass band; and a capacitor (C) that is serially arranged on a connection path between the common terminal () and the filter (H). When the filter (H) is regarded as a capacitance, the Q value of the capacitor (C) in the first pass band is higher than the Q value of the capacitance in the first pass band.
