Abstract
A multiplexer includes a common terminal, reception output terminals (and), a filter () that is connected between the common terminal and the reception output terminal (), a filter () that is connected between the common terminal and the reception output terminal () and has a pass band different from a pass band of the filter (), and an impedance matching circuit that is arranged between the common terminal and the filter (). The impedance matching circuit includes a parallel-arm resonator that is connected between a node (N) on a path connecting the common terminal to the filter () and a ground.
