Kind Code:
A1
Abstract:
This multiplexer (1) is provided with: a common connection terminal (60); an inductance element (61), one end of which is connected to a connection path between an antenna element (2) and filters (11-14) that are connected to the common connection terminal (60) and have passbands different from each other; and an inductance element (62), one end of which is connected to the other end of the inductance element (61), and the other end of which is connected to a reference terminal. A parallel arm resonator (354) of a filter (13) among the filters (11-14) has an inductance element (363) that is connected in series at an end which is on the other side of one end that is connected to a connection path which connects a transmission input terminal (30a) and a transmission output terminal (30b) to each other. The other end of the inductance element (363), said other end being on the other side of the one end that is connected to the parallel arm resonator (354), is connected to a connection path which connects the inductance element (61) and the inductance element (62) to each other.
